Make STANDALONE_LOAD_ADDR configurable per board

2011-04-12T20:58:32+00:00

Rename STANDALONE_LOAD_ADDR into CONFIG_STANDALONE_LOAD_ADDR
and allow that the architecture-specific default value gets
overwritten by defining the value in the board header file.

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: Fix systems with MSR=0

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

u-boot BSP generates XILINX_USE_MSR_INSTR macro
even for system with MSR=0. That's why explicitly
check that MSR=1.

Replace "FLASH" strings with "Flash" or "flash"

2011-01-18T23:02:37+00:00

There's no compelling reason to have the output on bootup or the
"flinfo" command print "flash" in uppercase, so use the proper case
where appropriate.

microblaze: Fix bd_info pointer

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

Patch "Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value"
(sha1: 25ddd1fb0a2281b182529afbc8fda5de2dc16d96)
introduce GENERATED_GBL_DATA_SIZE which is sizeof aligned gd_t
(currently 0x40).
Microblaze configs used 0x40(128) because this place also contained
board info structure which lies on the top of ram.

U-Boot is placed to the top of the ram (for example 0xd7ffffff)
and bd structure was moved out of ram.

This patch is fixing this scheme with GENERATED_BD_INFO_SIZE
which swap global data and board info structures.

For example:
Current: gd 0xd7ffffc0, bd 0xd8000000
Fixed:   gd 0xd7ffffc0, bd 0xd7ffff90

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.

Switch from archive libraries to partial linking

2010-11-17T20:02:18+00:00

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOC

2010-10-29T19:32:07+00:00

By now, the majority of architectures have working relocation
support, so the few remaining architectures have become exceptions.
To make this more obvious, we make working relocation now the default
case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value

2010-10-26T19:05:30+00:00

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  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.
