sh: modify checkcpu() for SH-4A

2012-08-08T00:50:41+00:00

Even if using CPU is SH-4A, the previous code always put "SH4".
This patch fixes it.

sh: avoid multiple definition errors with cache funcs

2011-12-02T04:46:21+00:00

Recent builds for SH4 boards fail with a lot of errors like:
	cmd_mem.o: In function 'dcache_invalid_range':
	include/asm/cache.h:25: multiple definition of 'dcache_invalid_range'
	include/asm/cache.h:25: first defined here

This is due to the funcs being defined in the header, but not static
or inline or extern.  So move them to the sh4-specific cache.c file.

sh: only add -mno-fdpic if the compiler supports it

2011-12-02T04:46:20+00:00

Not all SuperH toolchains support -mno-fdpic.  Chances are good that if
the flag doesn't work, it isn't defaulting to the FDPIC ABI, so the flag
isn't needed.  So only add it if it is actually supported.

punt unused clean/distclean targets

2011-10-15T20:20:36+00:00

The top level Makefile does not do any recursion into subdirs when
cleaning, so these clean/distclean targets in random arch/board dirs
never get used.  Punt them all.

MAKEALL didn't report any errors related to this that I could see.

sh: sh2a: Add sh2a optimize to config.mk

2011-08-22T04:16:08+00:00

Only the optimization of sh2 had been supported up.
This adds the optimization of sh2a.

sh: Add Renesas rsk7264 board

2011-08-22T04:16:08+00:00

The rsk7264 (also know as rsk2+sh7264) is an SH2A based board
with 64MB NAND flash and 64MB SDRAM. It is very similar to the
rsk7203 board.

rename _end to __bss_end__

2011-03-27T17:18:37+00:00

Currently, _end is used for end of BSS section.  We want _end to mean
end of u-boot image, so we rename _end to __bss_end__ first.

sh: Add KEEP order to start.o section

2011-03-16T01:16:34+00:00

The start.o section is changed by --gc-section option of ld.
Of this using KEEP order, therefore, evade this problem.

Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGS

2011-01-25T21:22:30+00:00

Linker needs to use the proper endian/bfd flags even when doing partial linking.
LDFLAGS_u-boot sets linker option which is called it when U-boot is built
(u-boot final).
LDFLAGS sets necessary option by partial linking (use in cmd_link_o_target).

sh: Fix build in start.S

2010-11-30T00:30:26+00:00

By commit 6d8962e814c15807dd6ac5757904be2a02d187b8,
label of _start was not usable in start.S and build fail.
This change label from  _start to _sh_start.
