Move DECLARE_GLOBAL_DATA_PTR to file scope

2010-12-21T10:33:36Z

It can be optimised out by the compiler otherwise resulting in obscure errors like a board not booting. This has been documented in README since 2006 when these were first fixed up for GCC 4.x.

ARM: */start.S: use canonical asm syntax

omap3: emif|sdrc: use a single global data define

2010-12-11T16:41:42Z

DECLARE_GLOBAL_DATA_PTR declarations in functions are inherently troublesome with various compilers (e.g. gcc 4.5) Signed-off-by: Nishanth Menon Signed-off-by: Sandeep Paulraj

OMAP: Timer: Replace bss variable by gd

2010-12-11T15:50:48Z

Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss values in the OMAP timer driver. The usage of bss values in drivers before initialisation of bss is forbidden. In that special case some data in .rel.dyn gets corrupted.

davinci: Rewrite timer.c to use tbl/tbu emulation variables in gd

2010-12-11T15:46:46Z

This change allows the davinci timer functions to be used before relocation since it avoids using static variables prior to BSS being made available. The code is based on that used in the at91 timers, modified to use a davinci specific hardware timer. It also maintains reset_timer() to allow deprecated timer usage to continue to work (for example, in nand_base.c) Signed-off-by: Nick Thompson Tested-by: Ben Gardiner Tested-by: Sudhakar Rajashekhara Tested-by: Sandeep Paulraj Signed-off-by: Sandeep Paulraj

armv7: fix relocation skip

2010-12-09T10:01:16Z

I doubt the stack_setup() was defective before: we load the current location of _start and compare against destination of relocate_code(). If we are already there we shoud skip the relocation and jump over to clear_bss. Before the clear_bss was also skipped. Signed-off-by: Andreas Bie�mann

arm: fixloop(): do not use r8 for relocation

2010-12-09T10:01:15Z

r8 is used for global_data and should therefore be left alone! For C code the compiler flag --fixed-r8 does the job, but in assembler we need to be aware of that fact. Signed-off-by: Andreas Bie�mann

arm: relocate_code(): do not set register useless

2010-12-09T10:01:15Z

In case we are still at relocation target address before relocation we do not need to load the registers needed for relocation. We should instead skip the whole relocation part and jump over to clear_bss immediately. Signed-off-by: Andreas Bie�mann

arm: copy_loop(): use scratch register

2010-12-09T10:01:14Z

This patch uses r1 as scratch register for copy_loop(). Therefore we do not longer need r7 for the storage of relocate_code()'s 'addr_moni' (the destination address of relocation). Therefore r7 can be used later on for other purposes. Signed-off-by: Andreas Bie�mann
