Wed Mar 26 07:03:19 CET 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

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
