* microblaze: Support stack protection featureMichal Simek2015-01-21-0/+4
| | | | | | | Ensure that stack didn't rewrite important part of u-boot. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* microblaze: Enable hardware exception by defaultMichal Simek2015-01-21-1/+1
| | | | | | | Enable hardware exception by default to be able to handle it. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* microblaze: Add SPL supportMichal Simek2014-02-04-0/+12
| | | | | | | Add support for U-BOOT SPL. NOR and RAM mode are supported. There are 3 images in NOR flash. u-boot.img, dtb and kernel. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

* microblaze: Flush caches before enabling themMichal Simek2012-11-07-0/+6
| | | | | | | | Flushing caches is necessary because of soft reset which doesn't clear caches. Signed-off-by: Michal Simek <monstr@monstr.eu> Reviewed-by: Marek Vasut <marex@denx.de>
* microblaze: Clean microblaze initializationMichal Simek2012-09-11-1/+1
| | | | | | | | | Move board specific function to board_init function in board/ folder Remove externs from generic board.c Use board_init_f function in board.c file. Signed-off-by: Michal Simek <monstr@monstr.eu> Acked-by: Stephan Linz <linz@li-pro.net>
* microblaze: intc: Clear interrupt codeMichal Simek2012-07-10-2/+0
| | | | | | | | | Clear and prepare for device-tree driven configuration. Remove CONFIG_SYS_INTC_0 definition Use dynamic allocation instead of static. Signed-off-by: Michal Simek <monstr@monstr.eu> Acked-by: Simon Glass <sjg@chromium.org>
* microblaze: Clean up reset asm codeMichal Simek2011-10-03-20/+5
| | | | | | | | - Remove code copying - Reset address is setup from first stage bootloader - Support reset vector setup on little endian Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Save and restore first unused vectorMichal Simek2011-10-03-2/+4
| | | | | | | | | | | | | Use one memory space to detect little/big endian platforms. The first unused address(0x28) is used instead 0x0 address (reset vectors). Detection rewrited reset vector setup from first stage bootloader. Workflow: 1. Store 0x28 to r7 2. Do little/big endian test 3. Restore r7 to 0x28 Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Setup MB vectors if feature is enable for u-bootMichal Simek2011-10-03-12/+22
| | | | | | | For example: Setup reset vectors if reset address is setup. Setup user exception vector if user exception is enabled Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Remove debug saving valueMichal Simek2011-10-03-2/+0
| | | | | | Forget to remove debug code. Signed-off-by: Michal Simek <monstr@monstr.eu>
* Coding Style cleanupWolfgang Denk2010-10-27-1/+1

* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-0/+1
| | | | | | | | | | | | | | | | | | CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-2/+2
| | | | | | | | | | | | The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

* microblaze: Support little-endian microblaze targetMichal Simek2010-10-12-9/+51
| | | | | | | Microblaze little-endian toolchain should export __MICROBLAZEEL__. Signed-off-by: Michal Simek <monstr@monstr.eu>
