is useful, if some of the configured banks are only
optionally available.
- CONFIG_FLASH_SHOW_PROGRESS
If defined (must be an integer), print out countdown
digits and dots. Recommended value: 45 (9..1) for 80
column displays, 15 (3..1) for 40 column displays.
- CFG_RX_ETH_BUFFER:
Defines the number of ethernet receive buffers. On some
ethernet controllers it is recommended to set this value
