Nicolas Pitre 158bc5af3d ARM: 5784/1: fix early boot machine ID mismatch error display
That code was refactored a long time ago, but one particular label
didn't get adjusted properly which broke the listing of supported
machines.

David Brown 31abdb7441 ARM: 5739/1: ARM: allow empty ATAG_CORE
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.

Catalin Marinas 88987ef91b Thumb-2: Add some .align statements to the .S files
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.

Russell King 37efe6427d [ARM] use asm/sections.h
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.

Catalin Marinas 93ed397011 [ARM] 5227/1: Add the ENDPROC declarations to the .S files
This declaration specifies the "function" type and size for various
assembly functions, mainly needed for generating the correct branch
instructions in Thumb-2.

Greg Ungerer 9c4c9f3879 [ARM] 4849/1: move ATAGS asm definitions
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).

Bill Gatliff 9d20fdd58e [ARM] 4423/1: add ATAGS support
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.
