2010-10-26Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk
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.

2010-10-19MX5: Remove dead code with ENABLE_IMPRECISE_ABORTJason Liu
This code section is dead due to we never define ENABLE_IMPRECISE_ABORT for MX5 Signed-off-by: Jason Liu <r64343@freescale.com>
2010-10-18Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk
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.

2010-10-17ARMV7: OMAP3: Fix bug in get_sdr_cs_offset()Steve Sakoman
This patch fixes a typo in the routine to calculate the cs offset based upon the contents of the SDRC cs_cfg register. This function mistakenly shifts the CS1STARTLOW field 17 bits right instead of 17 bits left. This hasn't been an issue to date because all OMAP3 boards currently are configured to have zeros in this field.

2010-10-11arm: bugfix: replace ble with blo in start.S filesAlbert Aribaud

2010-09-08ARMV7: OMAP3: Convert setup_auxcr() to pure asmMans Rullgard

2010-09-08ARMV7: OMAP3: Fix and clean up L2 cache enable/disable functionsMans Rullgard
On OMAP34xx ES1.0, the L2 enable bit can only be set in secure mode, so an SMC call to the ROM monitor is required. On later versions, and on newer devices, this bit is banked and we can set it directly. The code checked only the ES revision of the chip, and hence incorrectly used the ROM call on ES1.0 versions of other devices. This patch adds a check for chip family as well as revision, and also removes some code duplication between the enable and disable functions.
