[U-Boot-Users] "huge" (6 second) delay when booting linuxkernel (coldfire)

[Liew Tsi Chung]

Wolfgang,

I'm glad that you found the problem.

It must have been the early work that I did not change to use the new
CFG_BOOTMAPSZ. Now, the current repository has the new CFG_BOOTMAPSZ.

Found the problem.

It was a wrong CFG_BOOTMAPSZ, seems to have been a relic from my very
first try in porting to MCF53xx. With the correct line:

#define CFG_BOOTMAPSZ		(CFG_SDRAM_BASE + (CFG_SDRAM_SIZE <<
20))

Booting works fast as it should. (This new CFG_BOOTMAPSZ came from
M5329EVB.h).
