# Configuration file for fw_(printenv/setenv) utility.
# Up to two entries are valid, in this case the redundant
# environment sector is assumed present.
# Notice, that the "Number of sectors" is ignored on NOR and SPI-dataflash.
# Futhermore, if the Flash sector size is ommitted, this value is assumed to
# be the same as the Environment size, which is valid for NOR and SPI-dataflash

# NOR example
# MTD device name	Device offset	Env. size	Flash sector size	Number of sectors
/dev/mtd1		0x0000		0x4000		0x4000
/dev/mtd2		0x0000		0x4000		0x4000

# MTD SPI-dataflash example

fw_env.config: Correct "fw_saveenv" to "fw_setenv". Fix a comment in the fw_env.config file, no functional change. Signed-off-by: Robert P. J. Day <rpjday@crashcourse.ca> 2013-01-31 02:06:40 +00:00			`# Configuration file for fw_(printenv/setenv) utility.`

* Restrict baudrate settings on LWMON to higher speeds when watchdog is on * Update baudrate in bd_info when it gets changed * Add watchdog trigger points while waiting for serial port (so far only 8xx -- needed on LWMON with 100ms watchdog) * Improve command line tool to access the U-Boot's environment (figuration of the utility, using a config file) 2003-01-11 09:48:40 +00:00			`# environment sector is assumed present.`
Add support for dataflash to U-boot environment settings tool. * The sector size for SPI-dataflash (like AT45 flashes) are not always a power-of-2. So, the sector calculations are rewritten such that it works for either power-of-2 as any size sectors. * Make the flash sector size optional in case it is the same value as the environment size.
