2This file contains basic information on the port of U-Boot to TQM8260.
3All the changes fit in the common U-Boot infrastructure, providing a
4new TQM8260-specific entry in makefiles. To build U-Boot for TQM8260,
5type "make TQM8260_config", edit the "include/config_TQM8260.h" file
6if necessary, then type "make".

401- upgraded Flash support (added support for the following chips:
402 AM29LV800T/B, AM29LV160T/B, AM29DL322T/B, AM29DL323T/B)
403- BCR tweakage for the 8260 bus mode
404- SIUMCR tweakage enabling the MI interrupt (IRQ7)
405
406To simplify switching between the bus modes, a new configuration
407option (CONFIG_BUSMODE_60x) has been added to the "config_TQM8260.h"
408file. If it is defined, BCR will be configured for the 60x mode,
409otherwise - for the 8260 mode.
410
411Concerning the SIUMCR modification: it's hard to predict whether it
412will induce any problems on the other (60x mode) board. However, the
413problems (if they appear) should be easy to notice - if the board
414does not boot, it's most likely caused by the DPPC configuration in
415SIUMCR.
