sh: Remove compressed kernel libgcc dependency.

2011-06-06T08:57:58+00:00

SH-2A is unable to combine the kernel and libgcc objects due to
fundamental disagreements over FDPIC settings. As the kernel already
contains all of the libgcc bits broken out, there's not much need to
bother with the linking anymore, as everything can already be derived
from the lib dir.

This simply plugs in the necessary bits to ensure that everything is
built uniformly, enabling us to wean the compressed build off of explicit
libgcc linking.

mmc: Add MMC_PROGRESS_*

2011-03-24T16:24:57+00:00

This is my second attempt to make this enum generally available.
The first attempt added MMCIF_PROGRESS_* to include/linux/mmc/sh_mmcif.h.
However this is not sufficiently generic as the enum will be
used by SDHI boot code.

sh: Enable CONFIG_GCOV_PROFILE_ALL for sh

2011-02-15T07:47:17+00:00

This patch enables gcov kernel profiling over the whole kernel for sh.
Profiling of specific files individually already worked. A handful of
files have to be explicitly excluded from the profiling to avoid
breaking things, notably pmb.c.

mmc, sh: Remove sh_mmcif_boot_slurp()

2010-12-08T07:24:28+00:00

As the only caller of sh_mmcif_boot_do_read() is
sh_mmcif_boot_slurp() the configuration portion of
sh_mmcif_boot_slurp() can be merged into sh_mmcif_boot_do_read().

Once this is done sh_mmcif_boot_slurp() is only a call
to sh_mmcif_boot_do_read() with platform specific information -
the offset that images are stored on MMC. So make the
sh_mmcif_boot_do_read() call directly from platform code
and remove sh_mmcif_boot_slurp() altogether.

sh: boot kernel with SR.BL set

2010-09-30T00:43:32+00:00

Update the SH kernel to keep SR.BL set until the VBR
register has been initialized. Useful to allow boot
of the kernel even though exceptions are pending.

Without this patch there is a window of time when
exceptions such as NMI are enabled but no exception
handlers are installed.

This patch modifies both the zImage loader and the
actual kernel to boot with BL=1, but the zImage
loader is modfied in such a way that the init_sr
value is unchanged to not break the zImage loader
provided by kexec.

Tested on sh7724 Ecovec and on the SH4AL-DSP core
included in sh7372.

sh: add romImage MMCIF boot for sh7724 and Ecovec V2

2010-05-31T04:11:54+00:00

This patch is V2 of the MMCIF romImage boot support
for sh7724 and the Ecovec board. With this patch
applied and CONFIG_ROMIMAGE_MMCIF selected the
romImage kernel image can be written to a MMC card
and booted directly by the sh7724 cpu.
