# HEAD: e9524fb97ab5b41b85e1d3408f8e513433798f3c efi/x86: Don't blow away existing initrd

The EFI changes for this cycle are:

- preliminary changes for RISC-V
- Add support for setting the resolution on the EFI framebuffer
- Simplify kernel image loading for arm64
- Move .bss into .data via the linker script instead of relying on symbol
annotations.
- Get rid of __pure getters to access global variables
- Clean up the config table matching arrays
- Rename pr_efi/pr_efi_err to efi_info/efi_err, and use them consistently
- Simplify and unify initrd loading
- Parse the builtin command line on x86 (if provided)
- Implement printk() support, including support for wide character strings
- Simplify GDT handling in early mixed mode thunking code
- Some other minor fixes and cleanups

Thanks,

Ingo
