From: Kuo-Jung Su <dantesu at faraday-tech.com>
These patches introduce Faraday A369 & Virtual SoC platform support.
Here are some public documents for your reference.
http://www.faraday-tech.com/html/Product/SoCPlatform/SoCreativeIII.htm
http://www.faraday-tech.com/html/documentation/index.html
There is also a QEMU based A369 emulator available at my github account:
https://github.com/dantesu1218/qemu.git
Here is quick start for QEMU + U-Boot:
1. Download the QEMU source tree
$ git clone -b qemu-1.5.1 https://github.com/dantesu1218/qemu.git
2. Build & Install the QEMU:
$ ./configure --target-list=arm-softmmu
$ make
$ make install
3. Launch u-boot with QEMU:
$ qemu-system-arm -M a369 -m 512M -nographic -kernel ~/u-boot-2014.01/u-boot
Changes for v9:
- Shrink the patch by dropping MMU/D-cache support, and see if we could get
this patch accepted ASAP.
- Replace the out-of-date A360 EVB with Faraday Virtual Machine (FVM).
- Build 'arch_preboot_os()' only when CONFIG_CMD_BOOTM is defined.
- Add do_go_exec() to override the default behavior of 'go' command.
- Make Faraday SoC helper files & ftsmc020 standalone changesets.
- Coding style cleanup.
Changes for v8:
- Revise MMU/D-cache support
- Revise Faraday SoC common configurations.
- Drop FTINTC020 interrupt controller support.
- Drop FTLCDC200 LCD controller support.
- Drop FTNANDC021 NAND flash controller support, it would be latter submitted
as a standalone patch set.
- Drop proprietary Faraday SPL support, the u-boot-spl would be adapted instead.
However because it depends on the FTNANDC021 patch set, so it would be submitted
after the FTNANDC021 patch set get committed.
Changes for v7:
- Update license to use SPDX identifiers.
- cfi_flash: drop the patch to unmap_physmem(),
because it's already applied.
- ftnandc021: put_unaligned() -> memcpy()
- ftnandc021: update ecc relatived function prototypes to fix
compile warnnings.
Changes for v6:
- Drop ethernet driver updates for ftmac110&ftgmac100,
because they are already commited.
- arch/arm/cpu/faraday/cpu.c:
struct ftwdt010_wdt __iomem *regs -> struct ftwdt010_wdt *regs
- arch/arm/cpu/faraday/cmd_bootfa.c: fix compiler warnning
- arch/arm/cpu/faraday/cmd_bootfa.c: use shorter paragraph
in commit message, and move the original statement into the
top of source file.
- ftnandc021: update README for CONFIG_SYS_FTNANDC021_TIMING
- ftnandc021: remove illegal type-punning
Changes for v5:
- Coding Style cleanup:
1. struct chip_regs __iomem *regs -> struct chip_regs *regs
2. Move Faraday specific APIs into asm/arch-faraday/*.h
- Fix Copyright notices (dates) throughout the patch
- Make 'arm: dma_alloc_coherent: malloc() -> memalign()' as a separate patch
- Make 'cfi_flash: use buffer length in unmap_physmem()' as a separate patch
- Define Faraday machine type in board's config header file
- Add the rationale to the command 'bootfa'
- Add myself as the maintainer for Faraday A360/A369 in MAINTAINERS.
- Chain the video:FTLCDC200 back to this patch series.
- Chain the nand:FTNANDC021 back to this patch series.
- Chain the net:FTGMAC100 & FTMAC110 back to this patch series.
- Update Faraday Firmware Image Format:
1. Drop u-boot image support to simplify the design.
Since it's not possible for the hard-wired ROM code of A360/A369
to support U-boot images. And the real bootloader for A360/A369
is actually Faraday bootcode2, rather than U-Boot.
2. Add image creation timestamp
- Update 'arch/arm/cpu/faraday/start.S' with the new design, which move
relocation into 'arch/arm/lib/relocate.S'
- Drop i2c:FTI2C010 & spi:FTSSP010_SPI support. The corresponding patch
would restart after this patch series have been accepted.
- Revise IRQ & MMU design: Now the exception table would be mapped to
0x00000000 as a small page(4KB), rather than runtime adjust after
relocation finished.
- Revise irq:FTINTC020 design, now the irq is always enabled inside
irq_install_handler().
- Revise clock management system
- Revise FTPWMTMR010 & FTTMR010 timer design:
1. Drop IRQ dependant implementation
2. Use gd->arch.timer_rate_hz for timer clock source
3. Use gd->arch.tbl for timestamp
Changes for v4:
- Coding Style cleanup.
- Break down the patch series:
- Patches without hard dependency to this series are now
seperate patches.
- Split up the patch into more logical changesets
(i.e. interrupt & timers are now split up)
- Drop the faraday/nand.h to remove dependency to ftnandc021
- Drop the faraday/mmc.h to remove dependency to ftsdc010
- Add change logs to each part of the patch series to make
patchwork be able to grab comments.
Changes for v3:
- Coding Style cleanup.
There is still one warnning reported by checkpatch.pl,
however it's too deep for me to fix it.
Here is the shapshot for it:
-----------------------------------------------------
WARNING: do not add new typedefs
#9735: FILE: include/lcd.h:258:
+typedef struct vidinfo {
-----------------------------------------------------
- Drop bit fields from c struct.
- Drop macros for wirtel()/readl(), call them directly.
- Always insert a blank line between declarations and code.
- Replace all the infinite wait loop with a timeout.
- Add '__iomem' to all the declaration of HW register pointers.
- cmd_boot.c: Make it a separate stand-alone patch.
- ftspi020: Make it a separate stand-alone patch.
- dma-mapping.h: Have the global data ptr declared outside functions.
- dma-mapping.h: Add #if...#else...#endif to dma_free_coherent().
- MMU/D-Cache: Drop static non-cached region, now we use
map_physmem()/unmap_physmem() for dynamic mappings.
- ftmac110: Make a correction to multi-line comment style
- ftmac110: Use random MAC address while having trouble
to get one from environment variables.
- ftmac110: Add comments to timing control registers.
- ftnandc021: Re-write this driver with ECC enabled and
correct column address handling for OOB read/write,
and fixing issused addressed by Scott.
- a36x_config: No more static global network configurations.
- a36x_config: Add a common file for the redundant configurations.
Changes for v2:
- Coding Style cleanup.
- Use readl(), writel(), clrsetbits_le32() to replace REG() macros.
- Use structure based hardware registers to replace the macro constants.
- Replace BIT() with BIT_MASK().
- echi-faraday: Remove debug codes.
- ftmac110: Remove debug codes.
- cache-cp15: Enable write buffer in write-through mode.
