[U-Boot] [PATCH 0/2] Enable pxe boot for mx53cx9020

[U-Boot] [PATCH 0/2] Enable pxe boot for mx53cx9020

[linux-kernel-dev at beckhoff.com]

From: Patrick Bruenn <p.bruenn@beckhoff.com>

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

[U-Boot] [PATCH 1/2] imx: cx9020: use fdt_addr_r and ramdisk_addr_r

[linux-kernel-dev at beckhoff.com]

From: Patrick Bruenn <p.bruenn@beckhoff.com>

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.
