9ed5dfa852 i.MX28: Fix initial stack pointer position
The patch:

  m28evk: Use GENERATED_GBL_DATA_SIZE
  commit 1084606c97

introduced usage of GENERATED_GBL_DATA_SIZE and calculation of initial stack
pointer position defived from that. Due to a small typo, the SP position moved
to 0x21f80, which is past the SRAM area. This didn't manifest on the real
hardware as the SRAM repeats there (address bits in the CPU being ignored).

Though this was caught in QEMU, where it crashed the emulator.

1fc3bbd17a mx28evk: Provide default values for SPI bus and chip select
Provide default values for SPI bus and chip select.

This allows the command "sf probe" to work without passing SPI bus and chip
select numbers as arguments.

ed97abed27 mx28evk: add SPI support
This patch adds SPI support for the MX28EVK. Support for
an optionally installed SPI flash is also added. An example
configuration for redundant envrionment from SPI flash is also
added but disabled by default.

This patch has been tested on a MX28EVK Rev. D with an installed
SST25VF032B 32Mbit SPI flash.
