[U-Boot-Users] U-boot for Mips 4KEC

Hi,

In the process of porting U-boot for Malta which uses mips 4Kec I discovered that the stack required for intial C environment can neither be obtained by some on-chip memory (IMMR in MPC8xx ) nor by using DCACHE in locked mode. Mips 4KC has the DCache locked mode support but Mips 4KEC has it only through external pin interface.

I am looking for a way of not using the C code till code has started running from RAM. But how do I get the value of gd(global data pointer) which U-boot expects? README file does not mention anything about mips registers which are specifially used for this purpose.

Thanks and Regards, Pooja
