Sun Mar 13 22:36:43 CET 2016
This commit add support for 96Boards Dragonboard410C.
It is board based on APQ8016 Qualcomm SoC, complying with
96boards specification.
Features (present out of the box):
- 4x Cortex A53 (ARMv8)
- 2x USB Host port
- 1x USB Device port
- 4x LEDs
- 1x HDMI connector
- 1x uSD connector
- 3x buttons (Power, Vol+, Vol-/Reset)
- WIFI, Bluetooth with integrated antenna
- 8GiB eMMC
U-Boot boots chained with fastboot in 64-bit mode.
For detailed build instructions see readme.txt in board directory.
Signed-off-by: Mateusz Kulikowski <mateusz.kulikowski at gmail.com>
Tested-by: Simon Glass <sjg at chromium.org>
---
Changes in v3:
- readme: Added info on how to enter fastboot mode and that
dtbTool is also part of skales. Added more explanation
on image generation.
- head: Add comment why it's needed, drop MZ EFI signature
that makes no sense on this particular SoC, fix confusing
entry point name (+update .lds file)
Changes in v2:
- Renamed CONFIG_DM_SPMI -> CONFIG_SPMI
- Removed extra enter in dragonboard file
- Added ULPI* to defconfig
- Added MAINTAINERS to board
- Cleaned up config file - use distro defaults/environment:
- Dropped multiple CONFIG_CMD* and other CONFIG_*
- Added distro env/config
- Dropped old boot commands
- Split dts - pm8916_gpio entries are taken directly from
Linux Dragonboard dts; Add handles for u-boot in -uboot.dtsi;
They will be removed once gpio drivers are converted to pinctrl.
- Renamed some pmic nodes, fixed dragonboard.c to find them properly.
- Added header and converted comments to c98-style in head.S
- Print error if pmic gpio node is not found.
Changes in v1:
- Add better help for dragonboard
- Move static structures to board_prepare_usb
- Add DM_SPMI to defconfig

+Build & Run instructions:
+
+1) Install mkbootimg and dtbTool from
+ git://codeaurora.org/quic/kernel/skales (15ece94f09 worked for me)
+2) Setup CROSS_COMPILE to aarch64 compiler
+3) make dragonboard410c_config
+4) make
+5) generate fake, empty ramdisk (can have 0 bytes)
+$ touch rd
+
+6) Generate qualcomm device tree table with dtbTool [1]
+$ dtbTool -o dt.img arch/arm/dts
+
+7) Generate Android boot image with mkbootimg [2]:
+$ mkbootimg --kernel=u-boot-dtb.bin --output=u-boot.img --dt=dt.img \
+ --pagesize 2048 --base 0x80000000 --ramdisk=rd --cmdline=""
+
+8) Enter fastboot (reboot board with vol- button pressed)
+
+9) Boot it:
+$ fastboot boot u-boot.img
+or flash as kernel:
+$ fastboot flash boot u-boot.img
+$ fastboot reboot
+
+
+What is working:
+- UART
+- GPIO (SoC)
+- SD
+- eMMC
+- Reset
+- USB in EHCI mode (usb starts does switch device->host, usb stop does the opposite)
+- PMIC GPIOS (but not in generic subsystem)
+- PMIC "special" buttons (power, vol-)
+
+What is not working / known bugs:
+- SDHCI is slow (~2.5MiB/s for SD and eMMC)
+
+[1] To boot any kernel image, Little Kernel requires valid device tree for the
+platform it runs on. dtbTool creates device tree table that Little Kernel scans.
+Later on proper device tree is passed to next boot stage.
+Full device tree is not required to boot u-boot. Enough would be:

+
+but for simplicity (and because size of image is not that critical) we use
+existing Qualcomm device trees.
+
+[2] Note that ramdisk is required, even if it is unused.
