2011-03-15microblaze: Do not copy reset vectors/manual reset vector setupMichal Simek2-6/+13
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.

2011-03-15microblaze: Fix _reset functionMichal Simek1-1/+1
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 <monstr@monstr.eu> Signed-off-by: John Williams <john.williams@petalogix.com>
2011-03-15microblaze: Fix microblaze init vectorsMichal Simek1-1/+4
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 <monstr@monstr.eu>

2011-03-09microblaze: Do not use "la" pseudo instruction - use addik insteadMichal Simek4-15/+15

2011-03-09microblaze: Remove r0_ram pointer and PTO alignmentMichal Simek5-163/+156
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 <monstr@monstr.eu>
2011-03-09microblaze: Do not use r0_ram space for syscall debuggingMichal Simek1-3/+16

2011-02-07microblaze: Fix msr instruction detectionMichal Simek2-10/+9
Fix msr instructions detection. The current code just use msrclr for loading msr content and compare it with proper MSR content. If msrclr is not implemented r8 contains pc address. Previous code wanted to use MSR carry bit but if msrclr wasn't implemented carry wasn't cleared. Signed-off-by: Michal Simek <monstr@monstr.eu>
2011-02-07microblaze: Fix asm compilation warningMichal Simek1-2/+2

2011-02-04of/pci: move of_irq_map_pci() into generic codeSebastian Andrzej Siewior1-77/+0

2011-01-28microblaze: Fix unaligned issue on MMU system with BS=0 DIV=1Michal Simek1-4/+0
Unaligned code use shift for finding register operand. There is used BSRLI(r8,r8,2) macro which is expand for BS=0, DIV=1 by ori rD, r0, (1 << imm); \ idivu rD, rD, rA but if rD is equal rA then ori instruction rewrite value which should be devide. The patch remove this macro which use idivu instruction because idivu takes 32/34 cycles. The highest shifting is 20 which takes 20 cycles. Signed-off-by: Michal Simek <monstr@monstr.eu>
2011-01-28microblaze: Fix DTB passing from bootloaderMichal Simek1-2/+12
Little endian system needs to check OF_DT_HEADER but it is swapped because it is in big-endian. Microblaze LE provides lwr instruction which loads magic number in BIG endian format which can be compared. There is used the fact that if you write 0x1 as word and load it as byte then you get for big-endian zero and 1 for little-endian. Signed-off-by: Michal Simek <monstr@monstr.eu>
2011-01-15dt/flattree: Return virtual address from early_init_dt_alloc_memory_arch()Grant Likely1-2/+2

There is necessary to flush dcache and invalidate icache for address where breakpoint (brki r16, 0x18) was. The reason is that for some cases icache line still keeps brki instruction and it is not updated by origin instruction maintains by gdbserver. Signed-off-by: Michal Simek <monstr@monstr.eu>
