There is no such directory in U-Boot. I guess you mean u-boot-1.1.1/post - please be careful - '/' (hex 0x2F) followed by 'p' (hex 0x70) is NOT the same as '\p' which is an undefined escape sequence.
file cpu.c which is having the function "int cpu_post_test (int flags)". Till now I have analyzed that this function gets called for the POST of the CPU, but from there I didn't find any link to processor specific Test ....Since each processor would have different instruction set then how the generic CPU POST would do the job for all kind of processors. In the entire Source Code I didn't find processor -mpc8266 related POST code.
The existing POST code has not been generalized yet. So far, the full support is only available for MPC8xx processors.
I just want to make it sure that whether the cpu.c file defined in folder "u-boot-1.1.1\post" will also do the POST for the mpc8266. Please make it
No, it will not.
very clear, Do I need to make any changes anywhere so that the POST code written in the u-boot version 1.1.1 will work for mpc8266.
Yes, a lot of changes / extensions are needed.
