2011-03-09microblaze: Label MB 7.20.d as broken with WB cacheMichal Simek1-2/+2
MB version 7.20.d contains fault which is related with WB that's why error message will be shown. Signed-off-by: Michal Simek <[email protected]>
2011-03-09microblaze: Do not use "la" pseudo instruction - use addik insteadMichal Simek4-15/+15
"la" pseudo instruction is only translation to "addik". Use directly "addik" which is described in the MB reference guide. Signed-off-by: Michal Simek <[email protected]>
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 <[email protected]>
2011-03-09microblaze: Do not use r0_ram space for syscall debuggingMichal Simek1-3/+16
Remove syscall counting space from r0_ram. Use special syscall_debug_table pool for syscall statistic. Signed-off-by: Michal Simek <[email protected]>
2011-03-09microblaze: Optimize BE/LE bootup detectingMichal Simek1-5/+7
Save 0x1 word to rodata section and remove online value loading if DTB is passed from bootloader. It saves two asm instructions in bootup. Signed-off-by: Michal Simek <[email protected]>
2011-03-09microblaze: Do not use r0_ram space for hw exception debuggingMichal Simek1-4/+16

2011-02-23Merge branch 'linus' into x86/platformThomas Gleixner4-18/+23
Reason: Import mainline device tree changes on which further patches depend on or conflict. Trivial conflict in: drivers/spi/pxa2xx_spi_pci.c Signed-off-by: Thomas Gleixner <[email protected]>

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 <[email protected]>
2011-02-07microblaze: Fix asm compilation warningMichal Simek1-2/+2
Microblaze ASM doesn't support hex values for mfs instructions. /tmp/ccwiXVmt.s: Assembler messages: /tmp/ccwiXVmt.s:19: Warning: ignoring operands: x00 Signed-off-by: Michal Simek <[email protected]>
2011-02-04of/pci: move of_irq_map_pci() into generic codeSebastian Andrzej Siewior1-77/+0
There is a tiny difference between PPC32 and PPC64. Microblaze uses the PPC32 variant. Signed-off-by: Sebastian Andrzej Siewior <[email protected]> [[email protected]: Added comment to #endif, moved documentation block to function implementation, fixed for non ppc and microblaze compiles] Signed-off-by: Grant Likely <[email protected]>
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 <[email protected]>
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 <[email protected]>
2011-01-15dt/flattree: Return virtual address from early_init_dt_alloc_memory_arch()Grant Likely1-2/+2
The physical address is never used by the device tree code when allocating memory for unflattening. Change the architecture's alloc hook to return the virutal address instead. Signed-off-by: Grant Likely <[email protected]>

2011-01-03microblaze: Clear i/dcache for sw breakpointsMichal Simek1-0/+3
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 <[email protected]>

2010-10-21of/flattree: Eliminate need to provide early_init_dt_scan_chosen_archGrant Likely1-5/+0
This patch refactors the early init parsing of the chosen node so that architectures aren't forced to provide an empty implementation of early_init_dt_scan_chosen_arch. Instead, if an architecture wants to do something different, it can either use a wrapper function around early_init_dt_scan_chosen(), or it can replace it altogether. This patch was written in preparation to adding device tree support to both x86 ad MIPS. Signed-off-by: Grant Likely <[email protected]> Tested-by: David Daney <[email protected]>
2010-10-21microblaze: Support timer on AXI liteMichal Simek1-5/+16
New microblaze systems uses two buses. One for memories and flashes and the second for low-speed peripherals which can run on different CLK. This is the reason why the kernel is trying to read clock-frequency directly from node. If there is then the kernel will work with it. If not then cpu CLK is used. Signed-off-by: Michal Simek <[email protected]>
2010-10-21microblaze: Add support for little-endian MicroblazeMichal Simek5-11/+19
Microblaze little-endian toolchain exports __MICROBLAZEEL__ which is used in the kernel to identify little/big endian. The most of the changes are in loading values from DTB which is always big endian. Little endian platforms are based on new AXI bus which has impact to early uartlite initialization. Signed-off-by: Michal Simek <[email protected]>

2010-10-21microblaze: Do not compile early console support for uartlite if is disabledMichal Simek1-2/+7
Kconfig blocks to select any other early console support that's why this patch has no real impact on current kernel version. But it is done because of uart16550. Signed-off-by: Michal Simek <[email protected]>
