efi_loader: console support for color attributes

2017-10-12T15:24:25+00:00

Shell.efi uses this, and supporting color attributes makes things look
nicer.  Map the EFI fg/bg color attributes to ANSI escape sequences.
Not all colors have a perfect match, but spec just says "Devices
supporting a different number of text colors are required to emulate the
above colors to the best of the device’s capabilities".

efi_loader: Add mem-mapped for fallback

2017-10-12T15:22:58+00:00

When we don't have a real device/image path, such as 'bootefi hello',
construct a mem-mapped device-path.

This fixes 'bootefi hello' after devicepath refactoring.

efi_loader: don't increment part twice per loop

2017-10-10T16:14:05+00:00

Correct a mistake in the part number handling of commit
16a73b249d138fedeb188710533902ed7aac1ddc and only increment part once
per loop.

efi_loader: search all possible disk partitions

2017-10-10T07:56:04+00:00

When searching for partitions don't stop if a partition is not present
for a given partition number as there may be valid partitions after.

Search for up to MAX_SEARCH_PARTITIONS matching the other callers of
part_get_info().

This allows OpenBSD to boot via the efi_loader on rpi_3 again after
changes made after U-Boot 2017.09.  With MBR partitioning OpenBSD will
by default use the fourth partition for the 0xA6 (OpenBSD) partition.

Fix typo.

efi_loader: Fix disk dp's for pre-DM/legacy devices

2017-10-09T05:00:38+00:00

This fixes an issue with OpenBSD's bootloader, and I think should also
fix a similar issue with grub2 on legacy devices.  In the legacy case
we were creating disk objects for the partitions, but not also the
parent device.

efi_loader: avoid NULL dereference in efi_dp_match

2017-10-09T05:00:37+00:00

When calling bootefi hello twice a kernel dump occurs.

Neither bootefi hello nor bootefi selftest have an image
device patch. So do not try to dereference the NULL
value.

The size fields in the Simple Network Protocol are all
UINTN in the UEFI spec. So use size_t.

efi_loader: fix efi_net_get_status

2017-10-09T05:00:34+00:00

The returned interrupt status was wrong.

As out transmit buffer is empty we need to always set
EFI_SIMPLE_NETWORK_TRANSMIT_INTERRUPT.

When we have received a packet we need to set
EFI_SIMPLE_NETWORK_RECEIVE_INTERRUPT.

Furthermore we should call efi_timer_check() to handle events.
