[PATCH v6 102/102] x86: Add chromebook_coral
Simon Glass
sjg at chromium.org
Sat Dec 7 05:43:15 CET 2019
Add support for coral which is a range of Apollo Lake-based Chromebook
released in 2017. This also includes reef released in 2016, since it is
based on the same SoC.
Signed-off-by: Simon Glass <sjg at chromium.org>
---
Changes in v6:
- Add a comment about the need for board_run_command()
- Use generic gpio compatible string
Changes in v5:
- Add gpio-controller to GPIO nodes
- Comment out GPIOs in the fsp_s node since we don't use them yet
- Correct CPU ACPI IDs
- Use a define for ACPI base address
Changes in v4:
- Add u-boot,skip-auto-config-until-reloc property to PCI
- Drop duplicate commit 'Create a new sandbox_pci_read_bar() function'
- New GPIO driver binding
- Set up LPC pads early
- Switch over to use pinctrl for pad init/config
- Update documentation with more detailed memory map
- Use hyphen for device-tree properties
- apollolake -> Apollo Lake
Changes in v3:
- Ad FSP-S support
- Add CONFIG_TPL_X86_ASSUME_CPUID to reduce code size
- Add Chrome OS EC support
- Add a proper SPI node and make the SPI flash node a child
- Add bootstage support
- Add more documentation
- Add spi alias in device tree
- Disable the bootcommand since it does nothing useful on coral
- Don't enable SPI flash in TPL by default
- Drop CONFIG_SPL_NET_SUPPORT
- Drop patch '86: timer: Reduce timer code size in TPL on Intel CPUs'
- Drop patch 'dm: core: Don't include ofnode functions with of-platdata'
- Drop patch 'spi: sandbox: Add a test driver for sandbox SPI flash'
- Drop patch 'spl: Allow SPL/TPL to use of-platdata without libfdt'
- Drop patch 'x86: apollolake: Add definitions for the Intel Fast SPI interface'
- Drop patch 'x86: timer: Set up the timer in timer_early_get_count()'
- Enable video and USB3
- Reduce amount of early-pad data in TPL
- Tidy up the pad settings in the device tree
- Use a zero-based tsc timer
Changes in v2: None

+ This is a range of Intel-based laptops released in 2018. They use an
+ Intel Apollo Lake SoC. The design supports WiFi, 4GB to 16GB of
+ LPDDR4 1600MHz SDRAM, PCIe WiFi and Bluetooth, eMMC (typically 32GB),
+ up two cameras (front-facing 720p and another 5MP option), USB SD
+ reader, microphone and speakers. It also includes two USB 3 Type A and
+ two Type C ports. The latter are used as power input and can also
+ charge external devices as well as a 4K external display. There is a

+Chromebook Coral
+================
+
+Coral is a Chromebook (or really about 20 different Chromebooks) which use the
+Intel Apollo Lake platform (APL). The 'reef' Chromebooks use the same APL SoC so
+should also work. Some later ones based on Glacier Lake (GLK) need various
+changes in GPIOs, etc. but are very similar.
+
+It is hoped that this port can enable ports to embedded APL boards which are
+starting to appear.
+
+Note that booting U-Boot on APL is already supported by coreboot and
+Slim Bootloader. This documentation refers to a 'bare metal' port.
+
+
+Boot flow - TPL
+---------------
+
+Apollo Lake boots via an IFWI (Integrated Firmware Image). TPL is placed in
+this, in the IBBL entry.
+
+On boot, an on-chip microcontroller called the CSE (Converged Security Engine)
+sets up some SDRAM at ffff8000 and loads the TPL image to that address. The
+SRAM extends up to the top of 32-bit address space, but the last 2KB is the
+start16 region, so the TPL image must be 30KB at most, and CONFIG_TPL_TEXT_BASE
+must be ffff8000. Actually the start16 region is small and it could probably
+move from f800 to fe00, providing another 1.5KB, but TPL is only about 19KB so
+there is no need to change it at present. The size limit is enforced by
+CONFIG_TPL_SIZE_LIMIT to avoid producing images that won't boot.
+
+TPL (running from start.S) first sets up CAR (Cache-as-RAM) which provides
+larger area of RAM for use while booting. CAR is mapped at CONFIG_SYS_CAR_ADDR
+(fef00000) and is 768KB in size. It then sets up the stack in the botttom 64KB
+of this space (i.e. below fef10000). This means that the stack and early
+malloc() region in TPL can be 64KB at most.
+
+TPL operates without CONFIG_TPL_PCI enabled so PCI config access must use the
+x86-specific functions pci_x86_write_config(), etc. SPL creates a simple-bus
+device so that PCI devices are bound by driver model. Then arch_cpu_init_tpl()
+is called to early init on various devices. This includes placing PCI devices
+at hard-coded addresses in the memory map. PCI auto-config is not used.
+
+Most of the 16KB ROM is mapped into the very top of memory, except for the
+Intel descriptor (first 4KB) and the space for SRAM as above.
+
+TPL does not set up a bloblist since at present it does not have anything to
+pass to SPL.
+
+Once TPL is done it loads SPL from ROM using either the memory-mapped SPI or by
+using the Intel fast SPI driver. SPL is loaded into CAR, at the address given
+by CONFIG_SPL_TEXT_BASE, which is normally fef10000.
+
+Note that booting using the SPI driver results in an TPL image that is about
+26KB in size instead of 19KB. Also boot speed is worse by about 340ms. If you
+really want to use the driver, enable CONFIG_APL_SPI_FLASH_BOOT and set
+BOOT_FROM_FAST_SPI_FLASH to true[2].
+
+
+Boot flow - SPL
+---------------
+
+SPL (running from start_from_tpl.S) continues to use the same stack as TPL.
+It calls arch_cpu_init_spl() to set up a few devices, then init_dram() loads
+the FSP-M binary into CAR and runs to, to set up SDRAM. The address of the
+output 'HOB' list (Hand-off-block) is stored into gd->arch.hob_list for parsing.
+There is a 2GB chunk of SDRAM starting at 0 and the rest is at 4GB.
+
+PCI auto-config is not used in SPL either, but CONFIG_SPL_PCI is defined, so
+proper PCI access is available and normal dm_pci_read_config() calls can be
+used. However PCI auto-config is not used so the same static memory mapping set
+up by TPL is still active.
+
+SPL on x86 always runs with CONFIG_SPL_SEPARATE_BSS=y and BSS is at 120000
+(see u-boot-spl.lds). This works because SPL doesn't access BSS until after
+board_init_r(), as per the rules, and DRAM is available then.
+
+SPL sets up a bloblist and passes the SPL hand-off information to U-Boot proper.
+This includes a pointer to the HOB list as well as DRAM information. See
+struct arch_spl_handoff. The bloblist address is set by CONFIG_BLOBLIST_ADDR,
+normally 100000.
+
+SPL uses SPI flash to update the MRC caches in ROM. This speeds up subsequent
+boots. Be warned that SPL can take 30 seconds without this cache! This is a
+known issue with Intel SoCs with modern DRAM and apparently cannot be improved.
+The MRC caches are used to work around this.
+
+Once SPL is finished it loads U-Boot into SDRAM at CONFIG_SYS_TEXT_BASE, which
+is normally 1110000. Note that CAR is still active.
+
+
+Boot flow - U-Boot pre-relocation
+---------------------------------
+
+U-Boot (running from start_from_spl.S) starts running in RAM and uses the same
+stack as SPL. It does various init activities before relocation. Notably
+arch_cpu_init_dm() sets up the pin muxing for the chip using a very large table
+in the device tree.
+
+PCI auto-config is not used before relocation, but CONFIG_PCI of course is
+defined, so proper PCI access is available. The same static memory mapping set
+up by TPL is still active until relocation.
+
+As per usual, U-Boot allocates memory at the top of available RAM (a bit below
+2GB in this case) and copies things there ready to relocate itself. Notably
+reserve_arch() does not reserve space for the HOB list returned by FSP-M since
+this is already located in RAM.
+
+U-Boot then shuts down CAR and jumps to its relocated version.
+
+
+Boot flow - U-Boot post-relocation
+---------------------------------
+
+U-Boot starts up normally, running near the top of RAM. After driver model is
+running, arch_fsp_init_r() is called which loads and runs the FSP-S binary.
+This updates the HOB list to include graphics information, used by the fsp_video
+driver.
+
+PCI autoconfig is done and a few devices are probed to complete init. Most
+others are started only when they are used.
+
+Note that FSP-S is supposed to run after CAR has been shut down, which happens
+immediately before U-Boot starts up in its relocated position. Therefore we
+cannot run FSP-S before relocation. On the other hand we must run it before
+PCI auto-config is done, since FSP-S may show or hide devices. The first device
+that probes PCI after relocation is the serial port, in initr_serial(), so FSP-S
+must run before that. A corollary is that loading FSP-S must be done without
+using the SPI driver, to avoid probing PCI and causing an autoconfig, so
+memory-mapped reading is always used for FSP-S.
+
+It would be possible to tear down CAR in SPL instead of U-Boot. The SPL handoff
+information could make sure it does not include any pointers into CAR (in fact
+it doesn't). But tearing down CAR in U-Boot allows the initial state used by TPL
+and SPL to be read by U-Boot, which seems useful. It also matches how older
+platforms start up (those that don't use SPL).
+
+
+Performance
+-----------
+
+Bootstage is used through all phases of U-Boot to keep accurate timimgs for
+boot. Use 'bootstage report' in U-Boot to see the report, e.g.:
+
+Timer summary in microseconds (16 records):
+ Mark Elapsed Stage

+Credits
+-------
+
+This is a spare-time project conducted slowly over a long period of time.
+
+Much of the code for this port came from Coreboot, an open-source firmware
+project similar to U-Boot's SPL in terms of features.
+
+Also see [2] for information about the boot flow used by coreboot. It is
+similar, but has an extra postcar stage. U-Boot doesn't need this since it
+supports relocating itself in memory.
