microblaze: Get early printk console earlier

2011-07-25T07:23:47Z

1. Register early console as standard console 2. Enable CON_BOOT console flag to ensure auto-unregistering by the kernel 3. remap_early_printk function remap physical console baseaddr to virtual space Usage specific function for console remap is done after memory initialization with IRQ turn off that's why there is not necessary to protect it. The reason for remapping is that the kernel use TLB 63 for 1:1 address mapping to be able to use console in very early boot-up phase. But allocating one TLB just for console caused performance degression that's why ioremaps create new mapping and TLB 63 is automatically released and ready to use.

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 msr instruction detection

2011-02-07T18:13:01Z

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

microblaze: Report if only one timer is used

2010-10-21T05:51:30Z

Kernel needs two timers because of clocksource and clockevent. It is better to show warning message directly on early console if available. If it isn't available kernel log buffer contains it. Signed-off-by: Michal Simek

of: Merge of_platform_bus_type with platform_bus_type

2010-07-24T15:57:51Z

of_platform_bus was being used in the same manner as the platform_bus. The only difference being that of_platform_bus devices are generated from data in the device tree, and platform_bus devices are usually statically allocated in platform code. Having them separate causes the problem of device drivers having to be registered twice if it was possible for the same device to appear on either bus. This patch removes of_platform_bus_type and registers all of_platform bus devices and drivers on the platform bus instead. A previous patch made the of_device structure an alias for the platform_device structure, and a shim is used to adapt of_platform_drivers to the platform bus. After all of of_platform_bus drivers are converted to be normal platform drivers, the shim code can be removed. Signed-off-by: Grant Likely Acked-by: David S. Miller

microblaze: Print early printk information to log buffer

2010-04-01T06:38:25Z

If early printk console is not enabled then all messages are written to log buffer. Signed-off-by: Michal Simek

microblaze: Move cache function to cache.c

2010-03-11T13:07:57Z

It is better to have init cache handling on one place. Signed-off-by: Michal Simek

microblaze: Add support for Xilinx PCI host bridge

2010-03-11T13:05:18Z

This patch is based on powerpc patch 64f16502475ddf663169369fffff6da9b10ea9fb We did some cleanups and removed powerpc parts. There is one new debug early listing function too. Exclude function is only in Debug options. We tested in on custom board. Signed-off-by: Michal Simek

microblaze: Support DMA

2010-03-11T12:56:29Z

Add DMA support for Microblaze. There are some part of this new feature: 1. Basic DMA support 2. Enable DMA debug option 3. Setup notifier Ad 1. dma-mapping come from powerpc and x86 version and it is based on generic dma-mapping-common.h Ad 2. DMA support debug features which is used in generic file. For more information please look at Documentation/DMA-API.txt Ad 3. notifier is very important to setup dma_ops. Without this part for example ll_temac driver failed because there are no setup dma operations. Signed-off-by: Michal Simek

microblaze: Invalidate dcache before enabling it

2010-02-08T10:39:18Z

We found that on write-trough kernel is necessary to do that invalidation. One WB is possible to use invalidation too. Signed-off-by: Michal Simek
