[U-Boot] [PATCH v3 0/7] overo: add SPL support

[U-Boot] [PATCH v3 0/7] overo: add SPL support

[Andreas Müller]

V1 -> V2
* cleanups: replace printf with one argument by puts [1-2]
* cleanups: remove unused macros and macro values / tabbing / remove FSF address [3]
* i2c: move all local variables to SRAM [4]
* OMAP SPL: call timer_init in s_init to make udelay work earlier [5]
* hint CONFIG_SYS_TEXT_BASE changed in commit message [6]
* remove log 'Texas Instruments Revision detection unimplemented' for overo [6]
* remove unintended whitespaces [6]
* send 'shut up' to TWL4030 to avoid corruption when reading board revision [6]
* use macros for overo revisions [6]
* don't separate SPL specific configurations [6]

V2 -> V3
* modify omap_rev_string [6]
* CONFIG_SYS_TEXT_BASE back to 0x80008000 [7]
* modify CONFIG_SYS_SPL_MALLOC_START / CONFIG_SYS_SPL_MALLOC_SIZE / 
  CONFIG_SPL_BSS_START_ADDR to avoid conflicts with CONFIG_SYS_TEXT_BASE [7]

[U-Boot] [PATCH v3 4/7] drivers/i2c/omap24xx_i2c.c: move all local variables to SRAM

[Andreas Müller]

At old overo boards TWL4030 RTC irq is connected to gpio112. Unfortunately
this pin is also used for revision detection. Therefore we need to send
shut-up to TWL4030 to avoid reading wrong revision. In SPL this must
be done before SDRAM is set up because the type of SDRAM is revision dependent.
By this patch it is ensured that all variables used by omap24xx_i2c.c are
located in SRAM.

__attribute__ ((...)) is a checkpatch warning, so I've changed this to

* timing data and i2c workaround for revision 0 boards taken from x-loader
* run-tested with overo revision 0 and 1 / boot from NAND and SDcard
* run-tested with x-loader

To fix some warnings.  In the future please make sure you don't add
any new warnings with your changes.  Thanks!
