[U-Boot-Users] Question on pre-loader to U-Boot

[Zhang, Chris (Ex CH01)]

Hello everyone,

I am using at91rm9200dk u-boot from ATMEL.

I noticed that ATMEL uses programs called loader.bin and boot.bin to load
U-Boot into SDRAM. The Load Address is 0x21f00000 (the upper 1M).

My question is how does this value is choosen for U-Boot? I guess it is
related to linker behavior of U-Boot (right?), but there is no clue to
conclude such kind of address. Thanks for any hints.

Regards,
zl
