I'm about to send an updated set of patches for mxc_spi re-factoring and the related cleanup stemming from the discussions in http://lists.denx.de/pipermail/u-boot/2012-January/116816.html
These are split into multiple patch sets as suggested by Dirk: http://lists.denx.de/pipermail/u-boot/2012-January/116865.html
Because these are all re-sends, I'm tagging them as "V6" as requested by Jason: http://lists.denx.de/pipermail/u-boot/2012-January/116894.html
I'm also including a "PART #" to make it clear which patches are grouped together.
-- Part 1 will contain basic support for translating between ordinal GPIO numbers and port:index forms. It is required for parts 2, 4, and 5
-- Part 2 (3 patches) re-factors mxc_spi by moving register declarations into their arch-specific headers. This changed from the previous submission by using GPIO_NUMBER() instead of the undefined IMX_GPIO_NR(). http://lists.denx.de/pipermail/u-boot/2012-January/116901.html
-- Part 3 (2 patches) allows a board to define default values for SPI ROM bus and chip-selects and add some documentation for the same. I believe these have already been approved by Mike Frysinger.
-- Part 4 defines defaults for the mx6qsabrelite board. Note that this is slightly different from previous submission by also changing a reference to GPIO_NUMBER(3,19) to use the new default value (CONFIG_SF_DEFAULT_CS).
-- Part 5 conditionally defines a configuration for use in booting and saving environment to SPI flash instead of SD card to make it easier to switch between them.
