* ARM: io: remove IO_SPACE_LIMIT from platforms with ISA/PCI and 64K windowRussell King2011-08-175-10/+0
| | | | | | | | | | Remove IO_SPACE_LIMIT definitions from platforms which have a well defined ISA or PCI, and has a 64K window. EBSA110 - well defined set of ISA devices. Footbridge, Integrator, IXP4xx, VT8500 - PCI platforms. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: io: add a default IO_SPACE_LIMIT definitionRussell King2011-08-171-0/+21
| | | | | | | Add a default IO_SPACE_LIMIT definition. Explain the chosen value and suggest why platforms would want to make it larger. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: io: RiscPC: eliminate private inb() et.al. definitionsRussell King2011-08-171-182/+8
| | | | | | | As we've got rid of the bit-31 set IO addresses, we can now use the standard inb() definitions and reduce the IO space limit to 64K. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* ARM: io: ecard: remove ioaddr() from ecard.cRussell King2011-08-173-29/+14
| | | | | | | | Remove ioaddr() usage from ecard.c, updating (and renaming) the constants in RiscPC's hardware.h to contain the proper translation. As this gets rid of the last ioaddr() usage, kill that too. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* ARM: io: s3c2410: remove ioaddr()Russell King2011-08-171-2/+0
| | | | | | | | There is only one user of ioaddr() in the kernel, and that is the Acorn expansion card core code. S3C2410 does not use this code, and so the definition of ioaddr() is redundant. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* | arm: remove stale export of 'sha_transform'Linus Torvalds2011-08-081-3/+0

* | arm: remove "optimized" SHA1 routinesLinus Torvalds2011-08-072-212/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 1eb19a12bd22 ("lib/sha1: use the git implementation of SHA-1"), the ARM SHA1 routines no longer work. The reason? They depended on the larger 320-byte workspace, and now the sha1 workspace is just 16 words (64 bytes). So the assembly version would overwrite the stack randomly. The optimized asm version is also probably slower than the new improved C version, so there's no reason to keep it around. At least that was the case in git, where what appears to be the same assembly language version was removed two years ago because the optimized C BLK_SHA1 code was faster.
