[U-Boot-Users] [PATCH] MPC8xx: Parameter Area Relocation Support for SPI, I2C and SMC controllers

[Vladimir Gurevich]

Hello Wolfgang,

This patch adds full support for parameter area relocation on MPC8xx. 
This is needed if you want to simultaneously use devices that have 
overlapping parameter areas, such as SCC1/I2C, SCC2/SPI, SCC3/SMC1, 
SCC4/SMC2 (SCCx should be in Ethernet mode). The details are in 
doc/README.mpc8xx_upatch.

Both ROM-based relocation solution and microcode patch are supported. 
Selection is automatic.

In addition to that, this patch contains some minor enhancements for 
MPC8xx SPI driver and "sspi" command, which were kind of difficult to 
separate (I had to do everything together in order to be able to test it).

Changelog entry

* Added support for I2C, SPI and SMC parameter area relocation on MPC8xx
* Modified MPC8xx SPI driver to make it compatible with sspi command
* Minor enhanements to "sspi" command for better compatibility with 
"eeprom" command
   Patch by Vladimir Gurevich <vag@paulidav.org>

Thanks,
Vladimir
