* microblaze: Remove !OF_CONTROL code for timer and interruptMichal Simek2016-04-04-22/+1
| | | | | | OF_CONTROL is enabled by default that's why this is dead code. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* microblaze: Read information about timer/interrupts from DTMichal Simek2016-04-04-1/+63
| | | | | | | Read information about timer and interrupts from DT. This is the first small step to move timer and intc to DM. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* microblaze: Remove empty file - cpu.cMichal Simek2016-01-27-10/+1
| | | | | | No need to have empty unused file in architecture code. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

* Fix board init code to respect the C runtime environmentAlbert ARIBAUD2016-01-13-2/+2
| | | | | | | | | | | | | board_init_f_mem() alters the C runtime environment's stack it is actually already using. This is not a valid behaviour within a C runtime environment. Split board_init_f_mem into C functions which do not alter their own stack and always behave properly with respect to their C runtime environment.

* microblaze: Add a TODO to call board_init_f_mem()Simon Glass2015-10-24-0/+2
| | | | | | | | This C function should be used to do the early memory layout and init. This is beyond my powers, so just add a TODO for the maintainer. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Michal Simek <michal.simek@xilinx.com>
* remove unnecessary version.h includesRob Herring2015-03-24-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various files are needlessly rebuilt every time due to the version and build time changing. As version.h is not actually needed, remove the include.

| | | | | | This is required for driver model. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* microblaze: spl: Do not call mem_malloc_init and use early allocMichal Simek2015-02-09-1/+5
| | | | | | | | | | | | This patch has some parts connected together: - Use _gd in bss section which is automatically cleared Location at SPL_MALLOC_END wasn't cleared at all - Use MALLOC_F_LEN(early alloc) instead of FULL MALLOC (mem_malloc_init is not called at all) - Simplify malloc and stack init. At the end of SPL addr is malloc area and below is stack Signed-off-by: Michal Simek <michal.simek@xilinx.com>

* microblaze: Do not use CONFIG_SYS_GENERIC_GLOBAL_DATAMichal Simek2015-02-09-0/+6
| | | | | | | | Because it is not compatible with DM where malloc_base has to be available early and init has to be done in ASM. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

* Refactor linker-generated arraysAlbert ARIBAUD2013-03-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

* microblaze: Fix compilation failure because of missing libdtsMichal Simek2012-11-08-0/+2
| | | | | | | | | | Microblaze platform can use CONFIG_OF_EMBED option but also it is necessary to support boards which don't want to use this option. U-Boot doesn't compile dts/libdts.o for #undef CONFIG_OF_EMBED case that's why it should be guarded by ifdef. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Flush caches before enabling themMichal Simek2012-11-07-5/+6

* common: Discard the __u_boot_cmd sectionMarek Vasut2012-10-22-8/+0
| | | | | | | | | | | The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

| | | | | | | | | | | | | This is minimum code required to be able to use device-tree for u-boot initialization. Currently only for device driver initialization.

* microblaze: avoid interrupt race conditionsStephan Linz2012-02-23-2/+2
| | | | | | | | | | | | | | The interrupt acknowledge action have to run after the registered interrupt handler. So we have a chance to bear out the corresponding interrupt request in the corresponding controller hardware. With this reordering, we optain a proper interrupt handling for level triggered interrupt sources -- for example the new axi_timer v1.02.a introduced in ISE 13.2.
