efi_loader: Check machine type in the image header

2018-04-06T07:28:01+00:00

Check FileHeader.Machine to make sure the EFI executable image is built
for the same architecture. For example, 32-bit U-Boot on x86 will print
an error message instead of loading an x86_64 image and crashing.

efi_loader: completely initialize network

2018-04-05T16:09:31+00:00

Add missing network initialization code.

Before the patch the network was only usable if a network command like
dhcp or tftp had beed executed.

This was visible when interrupting the console countdown and executing
bootefi selftest for vexpress_ca15_tc2_defconfig.

efi_loader: new functions to print loaded image information

2018-04-05T13:23:55+00:00

Introduce functions to print information about loaded images.

If we want to analyze an exception in an EFI image we need the offset
between the PC and the start of the loaded image.

With efi_print_image_info() we can print the necessary information for a
single image, e.g.

UEFI image [0xbffe6000:0xbffe631f] pc=0x138 '/\snp.efi'

efi_print_image_infos() provides output for all loaded images.

efi_loader: implement EFI_FILE_SYSTEM_INFO

2018-04-05T08:01:45+00:00

Implement the information type EFI_FILE_SYSTEM_INFO in the service
GetInfo() of the EFI_FILE_PROTOCOL.

The volume label is not available in U-Boot. As a work-around use the
partition name instead.

We generally use efi_uintn_t where the UEFI spec uses UINTN.
