[U-Boot] [PATCH v8 2/2] arm: A320: Add support for Faraday A320 evaluation board
Po-Yu Chuang
ratbert.chuang at gmail.com
Wed Nov 11 10:27:30 CET 2009
This patch adds support for A320 evaluation board from Faraday. This board
uses FA526 processor by default and has 512kB and 32MB NOR flash, 64M RAM.
FA526 is an ARMv4 processor and uses the ARM920T source in this patch.

---
v2:
move flash timing parameters to config header
do not call timer_init() in board_init()
remove interrupt_init() in board specific code
move soc-specific headers to include/asm-arm/arch-faraday/
use write32 in assembly
remove board/faraday/a320/u-boot.lds
move register bases to soc-specific headers
v3:
do not define network parameters in config file
v4:
keep list of MAINTAINERS sorted
cleanup Makefile
use get_ram_size() for auto-sizing and memory testing
formating
v5:
soc: a320, board: a320evb
move ram and flash base to soc-specific header
move reset_cpu to soc-specific code
no bank swap
v6: rebase
v7: rebase
v8:
rebase
fix compiler warning
no space between function name and parenthesis
