Auto-sizing?

Do we really, really need new, nonstandard LED commands?

"improves" is a bit terse - in which way is it improved? Is it faster,
more reliable, has smaller code, or what?
Please provide a little more description in the committ message.

A witty saying proves nothing, but saying  something  pointless  gets
people's attention.

As precedently announce this driver is now deprecated only bug fix
will be accepted

please take a look on the spi flash framework

could you be more specific about all this new command
and please add a readme

sorry, but my board does not boot by this branch.
Followed by the bootstrapper-"RomBOOT"-prompt just some cryptical characters
appear. Seems like the cpu clock is not initialized correctly.
The board uses an 16.0 Mhz crystal.
I configured as followed:

/* ARM asynchronous clock */
#define AT91_CPU_NAME		"AT91SAM9263"
#define AT91_MAIN_CLOCK		16000000	/* 16.0 MHz crystal */
#define CONFIG_SYS_HZ		1000		/* decrementer freq */

#define CONFIG_MEESC			1	/* Board is esd MEESC */
#define CONFIG_ARM926EJS		1	/* This is an ARM926EJS Core */
#define CONFIG_AT91SAM9263		1	/* It's an AT91SAM9263 SoC*/
#define CONFIG_ARCH_CPU_INIT		1
...


If I build from git://git.denx.de/u-boot.git branch master after applying
my patches, the board boots up correctly.

Best Regards,
Daniel

this code is not responsible to initialize the cpu clock
it just read and calculate dynamicly the differenct at91 clocks

if this code does not work please not that linux will have the same problem
so please fix you lowlevel_init or your at91bootstrap

this crystal can even be detected by cpu without specify it

try without this define, by letting the cpu detect it
