cover Enable pxe boot for mx53cx9020

From: Patrick Bruenn <[email protected]>

To make kernel development more easy on CX9020, this scripts enables pxe boot in the default bootscript. pxe boot is then used as a fallback in case there is no vmlinuz found on mmc.

Patrick Bruenn (2):
imx: cx9020: use fdt_addr_r and ramdisk_addr_r
imx: cx9020: try pxe boot, if no vmlinuz on mmc

PATCH 1/2 imx: cx9020: use fdt_addr_r and ramdisk_addr_r

From: Patrick Bruenn <[email protected]>

Replace fdtaddr and rdaddr variable names with u-boot standard names fdt_addr_r and ramdisk_addr_r.
This will make the use of pxe boot more easy.
