It seems that this patch breaks all other boards. I tried myself and
after preprocessing the .cfg file, the resulting file contains
structures that mkimage cannot process.

For example, building udoo:

MKIMAGE u-boot.imx

Invalid imximage commands Type - valid names are: BOOT_FROM,
BOOT_OFFSET, DATA, CSF, IMAGE_VERSION
Error: board/udoo/udoo.cfg.cfgtmp[44] - Invalid command(struct)

In fact, board/udoo/udoo.cfg.cfgtmp contains the structures from
/mx6-ddr.h (this patch):

# 15 "include/config.h" 2
# 23 "board/udoo/udoo.cfg" 2
# 1
"/home/stefano/Projects/imx/u-boot-imx/arch/arm/include/asm/arch/mx6-ddr.h"
1
# 15
"/home/stefano/Projects/imx/u-boot-imx/arch/arm/include/asm/arch/mx6-ddr.h"
struct mx6_mmdc_ioregs {
u32 mmdc_dram_dqm0;
u32 mmdc_dram_dqm1;
u32 mmdc_dram_dqm2;
u32 mmdc_dram_dqm3;
u32 mmdc_dram_dqm4;
u32 mmdc_dram_dqm5;
u32 mmdc_dram_dqm6;
u32 mmdc_dram_dqm7;
u32 mmdc_dram_cas;
u32 mmdc_dram_ras;

and then mkimage stops.

Best regards,
Stefano Babic
