1ab027cbf6 mx51evk: support new relocation scheme
This patch is to fix build breakage and support new relocation
scheme for mx51evk.

- Correct IRAM base address and add size definition

  The IRAM starts from 0x1FFE0000 on final revsion i.mx51 than
  0x1FFE8000 which is for older revision.

- Include imx-regs.h in mx51evk.h

  Definitions like CSD0_BASE_ADDR and IRAM_BASE_ADDR can be
  referred to.

- Define CONFIG_SYS_INIT_RAM_ADDR and CONFIG_SYS_INIT_RAM_SIZE

  They are used to define init RAM layout.

- Remove comment for CONFIG_SYS_GBL_DATA_SIZE which has been
  buried by Wolfgang's commit below

06982534b6 mx51evk: consolidate env for mmcboot and netboot
This patch is to consolidate default mx51evk env for two primary
boot modes, mmcboot and netboot.

It also cleans some unused env like netdev, uboot and redundant
env like loadaddr since CONFIG_LOADADDR already defines it.

25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

9f481e95ba MXC: Correct SPI_CPOL setting in SPI driver
The handling of the SPI_CPOL bit inside the SPI
driver was wrong. As reported by the manual,
the meaning of the SSPOL inside the
configuration register is the same as reported
by SPI specification (0 if low in idle, 1 is high
on idle). The driver inverts this logic.

Because this patch sets the logic as specified, it is required
to clear the CPOL bit in the configuration file to adapt
to the correct logic.

5e1fe88fe3 Moved board specific values in config file
The lowlevel_init file contained some hard-coded values
to setup the RAM. These board related values are moved into
the board configuration file.
