Description
Items to implement to improve boot time, based on LJ article by Christopher Hallinan.
1. Review omap3_beagle.h in uboot, disable unnecessary features to reduce uboot size. NAND support is not necessary in uboot since we can access it in the kernel and we don't use NAND during boot.
2. Remove all but required drivers in kernel, move rest to modules
3. Uncompress kernel on SD card
4. Get BogoMips value and passs on kernel command args (lpj=xxx). See "Calibrating delay..." message at boot time.
5. Possibly use a CRAMFS boot rootfs with an ext2 partition mounted later during boot.
