PATCH 1/1 MIPS: provide a default u-boot-spl.lds

Provide a default linker script for SPL binaries. Start address and size of text section and BSS section are configurable. All sections are arranged in a way that only relevant sections are kept in the code section for maximum size reduction. All other sections are kept but moved outside the code section to help with debugging.

I'm worried this will blow when you enable DM in SPL, since DM uses special section(s) to keep the driver linked lists in. You'll probably need to add something like KEEP(*(SORT(.u_boot_list*))); somewhere in there.

why should this blow?

Because the u-boot driver list will be discarded by linker and that will lead either to linker complaining about it or scary bugs at runtime.

But you are right, u_boot_list is missing.

Is the ifdef really necessary ? I think if the list is empty, the u_boot_list will just be an zero-length symbol and since both this and the image_copy_end are 4-byte aligned, there will be no wasted space.

yes, I also tested it with your with your CI20 patches. If I disable CONFIG_SPL_DM, there still is u_boot_list entry from the MMC driver which would waste 120 Bytes.

Provide a default linker script for SPL binaries. Start address and size of text section and BSS section are configurable. All sections are arranged in a way that only relevant sections are kept in the code section for maximum size reduction. All other sections are kept but moved outside the code section to help with debugging.
