| * microblaze: Fix __muldi3 function for little-endian.Michal Simek2011-01-032-121/+60Star
| | | | | | | | | | | | | | | | | | __muldi3 was written for big endian platforms. Code contained half word read/write instructions which are not compatible with little endian cpu. Asm __muldi3 implementation is replaced by C version. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * microblaze: Clear i/dcache for sw breakpointsMichal Simek2011-01-031-0/+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 <monstr@monstr.eu>

* | of/flattree: Add Kconfig for EARLY_FLATTREEStephen Neuendorffer2010-12-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device tree code is now in two pieces: some which can be used generically on any platform which selects CONFIG_OF_FLATTREE, and some early which is used at boot time on only a few architectures. This patch segregates the early code so that only those architectures which care about it need compile it. This also means that some of the requirements in the early code (such as a cmd_line variable) that most architectures (e.g. X86) don't provide can be ignored. Signed-off-by: Stephen Neuendorffer <stephen.neuendorffer@xilinx.com> [grant.likely@secretlab.ca: remove extra blank line addition] [grant.likely@secretlab.ca: fixed incorrect #ifdef CONFIG_EARLY_FLATTREE check] [grant.likely@secretlab.ca: Made OF_EARLY_FLATTREE select instead of depend on OF_FLATTREE] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <monstr@monstr.eu>

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.
