Tue Apr 1 10:46:59 CEST 2014
From: Kuo-Jung Su <dantesu at faraday-tech.com>
Faraday Virtual Machine (FVM) is a QEMU based emulator
which is designed for early stage software development
(i.e., IPL, SPL development).
Please check the link bellow for details:
https://github.com/dantesu1218/qemu/blob/qemu-1.5.1/hw/arm/faraday_fvm.c
Signed-off-by: Kuo-Jung Su <dantesu at faraday-tech.com>
CC: Albert Aribaud <albert.u.boot at aribaud.net>
---
Changes for v12:
- Add Linux legacy clock framework support (no common clock).
- Drop board_early_init_f()
- Coding style cleanup
Changes for v11:
- Fix boards.cfg (due to commit 3fa67050)
- Rename <asm/sizes.h> to <linux/sizes.h> (due to commit 1ace4022)
- Directly specify the timer object in 'arch/arm/cpu/faraday/fvm/Makefile'
instead of using CONFIG_FTTMR010 in 'arch/arm/cpu/faraday/Makefile'
Changes for v10:
- Nothing updates
Changes for v9:
- Initial commit
