Hi Magnus, Hi Morimoto-san, I wonder if this might
be sufficient to get MMCIF zboot working on mackerel.
This patch depends on
* ARM: 6515/1: Add zboot support for SuperH Mobile ARM
(merged into the devel branch of Russel King's linux-2.6-arm tree)
* ARM: 6514/1: mach-shmobile: Add zboot support for SuperH Mobile ARM
(merged into the devel branch of Russel King's linux-2.6-arm tree)
* MACH_MACKEREL (3211) being present in arch/arm/tools/mach-types
* ARM: mach-shmobile: mackerel: Add zboot support
* rfc v3: mmc, ARM: Add zboot from MMC support for SuperH Mobile ARM,
which depends on
* mmc, sh: Remove sh_mmcif_boot_slurp()
(merged into the common/mmcif branch of Paul Mundt's sh-2.6 tree)
* sh, mmc: Use defines when setting CE_CLK_CTRL
(merged into the common/mmcif branch of Paul Mundt's sh-2.6 tree)
* mmc, sh: Move MMCIF_PROGRESS_* into sh_mmcif.h
(merged into the common/mmcif branch of Paul Mundt's sh-2.6 tree)
