* ARM: 5784/1: fix early boot machine ID mismatch error displayNicolas Pitre2009-11-081-1/+1
| | | | | | | | | That code was refactored a long time ago, but one particular label didn't get adjusted properly which broke the listing of supported machines. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: 5739/1: ARM: allow empty ATAG_COREDavid Brown2009-10-021-1/+3
| | | | | | | | | | | | From: David Brown <davidb@quicinc.com> The ATAG_CORE is allowed to be empty. Although this is handled by parse_tag_core(), __vet_atags during startup rejects this tag unless it contains data. Allow the initial tag to be either the full size, or empty.

* Thumb-2: Implementation of the unified start-up and exceptions codeCatalin Marinas2009-07-241-5/+8
| | | | | | | This patch implements the ARM/Thumb-2 unified kernel start-up and exception handling code. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* Thumb-2: Add some .align statements to the .S filesCatalin Marinas2009-07-241-0/+2
| | | | | | | | Since the Thumb-2 instructions can be 16-bit wide, data in the .text sections may not be aligned to a 32-bit word and this leads to unaligned exceptions. This patch does not affect the ARM code generation. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* [ARM] use asm/sections.hRussell King2008-12-011-1/+1
| | | | | | | | Update to use the asm/sections.h header rather than declaring these symbols ourselves. Change __data_start to _data to conform with the naming found within asm/sections.h. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 5227/1: Add the ENDPROC declarations to the .S filesCatalin Marinas2008-09-011-9/+10
| | | | | | | | | This declaration specifies the "function" type and size for various assembly functions, mainly needed for generating the correct branch instructions in Thumb-2. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] move include/asm-arm to arch/arm/include/asmRussell King2008-08-021-1/+1
| | | | | | | Move platform independent header files to arch/arm/include/asm, leaving those in asm/arch* and asm/plat* alone. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4881/1: print unrecognised processor ID as part of failure messageLennert Buytenhek2008-04-191-1/+6
| | | | | | | | | If we fail to boot due to an unsupported processor ID, print the processor ID as part of the failure message. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Acked-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4849/1: move ATAGS asm definitionsGreg Ungerer2008-03-061-0/+3
| | | | | | | | | | | Move the definitions of ATAG_CORE and ATAG_CORE_SIZE in head.S to head-common.S. There is no use of these in head.S itself, but they are used in head-common.S. When building for the !CONFIG_MMU case these were not defined when compiling head-nommu.S (which includes head-common.S).

* [ARM] 4423/1: add ATAGS supportBill Gatliff2007-07-121-3/+37
| | | | | | | | | Examines the ATAGS pointer (r2) at boot, and interprets a nonzero value as a reference to an ATAGS structure. A suitable ATAGS structure replaces the kernel's command line. Signed-off-by: Bill Gatliff <bgat@billgatliff.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] nommu: start-up codeHyok S. Choi2006-03-271-0/+217
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>
