[U-Boot] uboot for MIPS: need help to skip relocate uboot and start uboot from RAM

Dear Pandurang Kale,

U-Boot does not "think" it is stored in flash - this is what you
configured.  If you know you're always loading it to a fixed RAM
address, you can use this as reference for TEXT_BASE instead.

No, you do NOT want to do thjat, as it would cripple U-Boot and remove
basic functionality from it.

Are you looking at recent code and working boards?

Do do not want to skip relocation.  U-Boot may need to auto-adjust
it's start address dynamically, depending on configuration, system
requirements and/or environment settings.
