Changes in v2:
- add Cc
- split up original patch series
Changes in v3:
- use clrsetbits() instead of clrbits()/setbits()
- remove dead code
- remove unnecessary #undef
Changes in v4:

+Booting from eSPI/eSDHC
+-----------------------
+
+The P1022 is capable of loading initialization code from a memory device that is
+connected to the eSPI or eSDHC controller interface. Booting is supported by the
+P1022 using an on-chip ROM which contains the basic device driver and the code
+to perform block copy to any target memory.
+
+Freescale offers a tool for building SD or SPI images, which is hosted here:
+http://git.freescale.com/git/cgit.cgi/ppc/sdk/boot-format.git
+
+For eSDHC:
+
+1. Build u-boot
+ make P1022DS_SDCARD_config
+ or
+ make P1022DS_36BIT_SDCARD_config
+ then
+ make
+
+2. Prepare SD card
+ boot_format config_ddr3_2gb_p1022ds.dat u-boot.bin -sd /dev/sd...
+
+3. Change dip-switch
+ SW4[5-8] = 0111
+
+4. Insert SD card and push RESET
+
+For eSPI:
+
+1. Build u-boot
+ make P1022DS_SPIFLASH_config
+ or
+ make P1022DS_36BIT_SPIFLASH_config
+ then
+ make
+
+2. Prepare binary image file
+ boot_format config_ddr3_2gb_p1022ds.dat u-boot.bin -spi spiimage.bin
+
+3. Program SPI memory device using u-boot
+ tftpboot $loadaddr spiimage.bin
+ sf probe
+ sf erase 0 +$filesize
+ sf write $fileaddr 0 $filesize
+
+3. Change dip-switch
+ SW4[5-8] = 0110
+
+4. Push RESET
