[U-Boot] [PATCH] OMAP4: speed up booting on Pandaboard

Thu Nov 4 10:38:16 CET 2010


Improved default config for OMAP4 Pandaboard for faster boot:
	-reduced environment size to speed up memory initialization;
	-USB TTY driver turned off;
	-tweaked blob load address to avoid image relocation (according to default uImage load address);
