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
