2007-05-08	[ARM] Ensure head text is always placed at the start of kernel	Russell King	1	-1/+1
	Commit 86c0baf123e474b6eb404798926ecf62b426bf3a highlighted that we may end up with the head text placed elsewhere in the kernel image. Introduce a new .text.head section to contain the initial kernel startup code, and always place this section at the beginning of the kernel image.

2006-11-30	[ARM] Include asm/elf.h instead of asm/procinfo.h	Russell King	1	-1/+0
	These files want to provide/access ELF hwcap information, so should be including asm/elf.h rather than asm/procinfo.h Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-28	[ARM] nommu: confirms the CR_V bit in nommu mode	Hyok S. Choi	1	-0/+5
	In nommu mode, the exception vector location depends on the platforms. Some of the implementations may have some special exception control forwarding method in their ROM/flash and for some of them has its own re-mapping mechanism by the h/w. This patch introduces a special configuration CONFIG_CPU_HIGH_VECTOR which turns on the CR_V bit in nommu mode. The CR_V bit is turned off by default. This feature depends on CP15 and does not supported by ARM740. Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27	[ARM] nommu: manage the CP15 things	Hyok S. Choi	1	-1/+6
	All the current CP15 access codes in ARM arch can be categorized and conditioned by the defines as follows: Related operation Safe condition a. any CP15 access !CPU_CP15 b. alignment trap CPU_CP15_MMU c. D-cache(C-bit) CPU_CP15 d. I-cache CPU_CP15 && !( CPU_ARM610 \|\| CPU_ARM710 \|\| CPU_ARM720 \|\| CPU_ARM740 \|\| CPU_XSCALE \|\| CPU_XSC3 ) e. alternate vector CPU_CP15 && !CPU_ARM740 f. TTB CPU_CP15_MMU g. Domain CPU_CP15_MMU h. FSR/FAR CPU_CP15_MMU For example, alternate vector is supported if and only if "CPU_CP15 && !CPU_ARM740" is satisfied. Signed-off-by: Hyok S.

2006-06-30	Remove obsolete #include <linux/config.h>	Jörn Engel	1	-1/+0

2006-06-25	[ARM] Remove MODE_(SVC\|IRQ\|FIQ\|USR) and DEFAULT_FIQ	Russell King	1	-1/+1
	DEFAULT_FIQ was entirely unused. MODE_* are just redefinitions of _MODE. Use _MODE instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-05-05	[ARM] 3496/1: more constants for asm-offsets.h	Uwe Zeisberger	1	-3/+1
	Patch from Uwe Zeisberger added the following constants: - MACHINFO_TYPE - MACHINFO_NAME - MACHINFO_PHYSIO - MACHINFO_PGOFFIO - PROCINFO_INITFUNC - PROCINFO_MMUFLAGS and removed their definition from head.S and head-nommu.S Signed-off-by: Uwe Zeisberger <Uwe_Zeisberger@digi.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-04-24	[ARM] nommu: trivial fixups for head-nommu.S and the Makefile	Hyok S. Choi	1	-1/+3
	This patch fix compilation problem of start-up codes. (head-nommu.S, arch/arm/kernel/Makefile) Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-03-27	[ARM] nommu: start-up code	Hyok S. Choi	1	-0/+83
	This patch adds nommu version start-up code head-nommu.S. The common part of the start-up codes is moved to head-common.S. Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
