sh/highmem: Remove all traces of unused cruft

2020-11-06T22:14:54+00:00

For whatever reasons SH has highmem bits all over the place but does not enable it via Kconfig. Remove the bitrot.

sh: remove sh5 support

2020-06-01T18:48:52+00:00

sh5 never became a product and has probably never really worked. Remove it by recursively deleting all associated Kconfig options and all corresponding files. Reviewed-by: Geert Uytterhoeven Signed-off-by: Arnd Bergmann Signed-off-by: Rich Felker

Revert "sh: Ensure fixmap and store queue space can co-exist."

2012-05-18T10:30:05+00:00

This reverts commit 20e7c297efeca0861adcca073a0d283da659834b. With store queues enabled the area above P4SEG has special properties from the MMU's point of view, which was causing fixmap failure. We'll have to do something else to satisfy the vmalloc range check. Signed-off-by: Paul Mundt

sh64: Kill off unused fixed I/O mapping window.

2012-05-14T06:16:11+00:00

This was reworked some time ago to go through fixmaps instead, leaving the range itself unused. As such, kill off the remaining references and hand over the remaining space for fixmaps directly. This also makes it possible to simplify the vmalloc fault case as we no longer have to care about the special section. Signed-off-by: Paul Mundt

sh: Ensure fixmap and store queue space can co-exist.

2012-05-14T06:11:35+00:00

At the moment the top of the fixmap space is calculated from P4SEG, which places it at the end of the store queue space when that API is enabled. Make sure we use P3_ADDR_MAX here instead to find the proper address limit. With this done, it's also possible to switch to the generic vmalloc address range check now that VMALLOC_START/END encapsulate the translatable areas that we care about. Signed-off-by: Paul Mundt

sh: fix up an off-by-1 in the number of early ioremap fixmaps.

2010-06-21T07:23:03+00:00

There was an off-by-1 in the begin/end of the ioremap fixmaps, leaving us with a spurious entry. In practice this wasn't a problem since we aligned on a PMD boundary anyways, but this makes it consistent with the intention and the other fixmaps. Signed-off-by: Paul Mundt

sh: Conserve fixmap slots when IOREMAP_FIXED=n.

2010-01-21T07:16:36+00:00

Presently the IOREMAP_FIXED fixmaps are always defined, even if the platform isn't capable of supporting it. Since we already have an ifdef for it, ifdef the entries, too. Signed-off-by: Paul Mundt

sh: Kill off the special uncached section and fixmap.

2010-01-21T07:05:25+00:00

Now that cached_to_uncached works as advertized in 32-bit mode and we're never going to be able to map < 16MB anyways, there's no need for the special uncached section. Kill it off. Signed-off-by: Paul Mundt
