Title:
  Kernel cmdline limited to 256 characters in pxeboot

Status in Linaro U-Boot:
  New
Status in “u-boot” package in Ubuntu:
  New

Bug description:
  The default # of characters allowed in the omap4 kernel is set at 512
  according to /usr/src/linux-headers-3.0.0-1200-omap4/include/asm-
  generic/setup.h, however u-boot only allows 256 on the append line in
  the pxe config.  With the panda, this is severely limiting due to the
  need to work around a known memory hole with  mem=456M@0x80000000
  mem=512M@0xA0000000.  Either the memory hole is left unmasked, which
  may cause random kernel oops during an image install, or netinstall
  cannot effectively be preseeded for full automation.

  Working length:
  append vram=32M mem=456M@0x80000000 mem=512M@0xA0000000 fixrtc debian-installer/framebuffer=false console=ttyO2,115200n8 url=http://master.gruenet/preseed/preseed.cfg locale=en_US setup/layoutcode=en_US console-setup/layoutcode=en_US auto netcfg/get_hostname=

  Failing length:
  append vram=32M mem=456M@0x80000000 mem=512M@0xA0000000 fixrtc quiet debian-installer/framebuffer=false console=ttyO2,115200n8 url=http://master.gruenet/preseed/preseed.cfg locale=en_US setup/layoutcode=en_US console-setup/layoutcode=en_US auto netcfg/get_hostname=

  Difference is the addition of "quiet" to reduce the noise level of
  kernel boot messages.
