Greetings,
Have a look at src/ram/ramtest.inc It is probably worthwhile to insert that before the uncompress and call it to see if the ram is REALLY there. The copy/uncompress to RAM does it blindly, so will happily 'succeed' even if there's no RAM there.

Hi, My image boots up to the following serial output message,

It says that it is jumpimg to LinuxBIOS, that means it has copied the images to RAM. So next step is to CALL(harwaremain). It is not jumping in to hardwaremain function.
From the linuxbios.map I found that address of hardwaremain function is
00000904 T hardwaremain
