efi_loader: initrddump: Actually use the custom CFLAGS

2022-03-31T17:06:17+00:00

It seems a copy'n'paste typo when tool had been introduced.
It has never had the 'exit' suffix in the file name. Hence,
the custom CFLAGS never been applied and, for example, BFD
linker complains:

  LD      lib/efi_loader/initrddump_efi.so
  ld.bfd: lib/efi_loader/initrddump.o: warning: relocation in read-only section `.text.efi_main'
  ld.bfd: warning: creating DT_TEXTREL in a shared object

Remove wrong 'exit' suffix from the custom CFLAGS variable.

efi_loader: initrddump: drain input before prompt

2022-03-26T06:46:21+00:00

Up to now the initrddump.efi application has drained the input after
showing the prompt. This works for humans but leads to problems when
automating testing. If the input is drained, this should be done before
showing the prompt.

efi_loader: nocolor command line attr for initrddump.efi

2022-03-26T06:46:21+00:00

initrddump.efi uses colored output and clear the screen. This is not
helpful for integration into Python tests. Allow specifying 'nocolor' in
the load option data to suppress color output and clearing the screen.

efi_loader: move dtbdump.c, initrddump.c to lib/efi_loader

2022-03-20T16:01:00+00:00

The tools dtbdump.efi and initrddump.efi are useful for Python testing even
if CONFIG_EFI_SELFTEST=n.

Don't clear the screen as it is incompatible with Python testing.

efi_loader: remove efi_disk_is_system_part()

2022-03-20T10:03:06+00:00

The block IO protocol may be installed on any handle. We should make
no assumption about the structure the handle points to.

efi_disk_is_system_part() makes an illegal widening cast from a handle
to a struct efi_disk_obj. Remove the function.

efi_loader: support booting via short-form device-path

2022-03-20T10:03:06+00:00

The boot manager must support loading from boot options using a short-form
device-path, e.g. one where the first element is a hard drive media path.

See '3.1.2 Load Options Processing' in UEFI specification version 2.9.
