  195. slightly different. see include/configs/hymod.h for an example

  209. linker script, selected via the LDSCRIPT, make variable, and to
  210. give an initial value to the OBJCFLAGS make variable
  211. - 8260 i2c enhancement:
  212. o correctly extends the timeout depending on the size of all
  213. queued messages for both transmit and receive
  214. o will not continue with receive if transmit times out
  215. o ensures that the error callback is done for all queued tx
  216. and rx messages
  217. o correctly detects both tx and rx timeouts, only delivers one to
  218. the callback, and does not overwrite an earlier error
  219. o logic in i2c_probe now correct
  220. - add "vprintf()" function so that "panic()" function can be
  221. technically correct

  678. - Adding URL for IEEE OUI lookup
  679. - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
  680. being defined.
  681. - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
  682. root-on-nfs macros are designed to switch how the default boot
