microblaze: avoid interrupt race conditions

2012-02-23T11:16:04+00:00

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.

microblaze: fix build failure due to undefined reference to `get_ticks'

2012-02-23T11:15:14+00:00

after commit "common: add possibility for readline_into_buffer
timeout" (sha1:9c34831) was applied. The Microblaze generic build
fails with error below:

common/libcommon.o: In function `cread_line':
/devel/u-boot/common/main.c:717: undefined reference to `get_ticks'
/devel/u-boot/common/main.c:717: undefined reference to `get_tbclk'

- Reset address is setup from first stage bootloader
- Support reset vector setup on little endian

microblaze: Save and restore first unused vector

2011-10-03T06:01:56+00:00

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

microblaze: Fix msr handling in interrupt_handler

2011-02-15T14:13:24+00:00

Fix ancient code which worked with MSR in a bad way.
Use rtid instruction which enable IRQs and jump.

microblaze: Disabling interrupt should return 1 if was enabled

2011-01-10T07:52:32+00:00

Microblaze implement enable/disable interrupts through MSR
that's why disable_interrupts function should return 1 when interrupt
was enabled. Return 0 when interrupt was disabled.
