microblaze: Trivial asm fix

2012-01-05T07:34:28Z

Just replace one dot with comma. New binutils can detect it. Signed-off-by: Michal Simek

microblaze: Do not copy reset vectors/manual reset vector setup

2011-03-15T09:59:00Z

Reset vector can be setup by bootloader and kernel doens't need to touch it. If you require to setup reset vector, please use CONFIG_MANUAL_RESET_VECTOR throught menuconfig. It is not possible to setup address 0x0 as reset address because make no sense to set it up at all. Signed-off-by: Michal Simek Signed-off-by: John Williams

microblaze: Fix _reset function

2011-03-15T09:58:44Z

If soft reset falls through with no hardware assisted reset, the best we can do is jump to the reset vector and see what the bootloader left for us. Signed-off-by: Michal Simek Signed-off-by: John Williams

microblaze: Fix microblaze init vectors

2011-03-15T09:58:34Z

Microblaze vector table stores several vectors (reset, user exception, interrupt, debug exception and hardware exception). All these functions can be below address 0x10000. If they are, wrong vector table is genarated because jump is not setup from two instructions (imm upper 16bit and brai lower 16bit). Adding specific offset prevent problem if address is below 0x10000. For this case only brai instruction is used. Signed-off-by: Michal Simek

microblaze: Do not use "la" pseudo instruction - use addik instead

2011-03-09T07:09:54Z

"la" pseudo instruction is only translation to "addik". Use directly "addik" which is described in the MB reference guide. Signed-off-by: Michal Simek

microblaze: Remove r0_ram pointer and PTO alignment

2011-03-09T07:09:54Z

r0_ram pool was used for saving/restoring register content if hw exception happen. This poll was replaced by pt_pool_space with PT_SIZE size. Based on this change SAVE_STATE_ARG_SPACE was removed which caused that PTO offset is zero that's why is also removed. r0_ram space was used as scratchpad by v850. In early Microblaze Linux developing phase was this part of code blindly copied. Signed-off-by: Michal Simek

microblaze: Do not use r0_ram space for syscall debugging

2011-03-09T07:09:54Z

Remove syscall counting space from r0_ram. Use special syscall_debug_table pool for syscall statistic. Signed-off-by: Michal Simek

Revert "microblaze: Simplify syscall rutine"

2010-11-18T12:13:52Z

This reverts commit 0e41c90908881a1b8205c66a66becec7d8d4eb4a. Break jffs2 rootfs because the patch removes syscall calling from kernel space. Signed-off-by: Michal Simek

microblaze: Fix r16 and r17 reg saving

2010-10-21T05:51:33Z

r16 and r17 should be saved across interrupt and exception handling. Signed-off-by: Michal Simek

microblaze: Clear return value in pt_regs

2010-10-21T05:51:29Z

Signal code uses r3 value which saved in restore_sigcontext to rt_sigframe but it require to be zeroed. If is not zero rt_sigframe contains wrong values. Signed-off-by: Michal Simek
