efi_loader: Rename EFI_RUNTIME_{TEXT, DATA} to __efi_runtime{, _data}

2016-10-19T07:01:54+00:00

Compiler attributes are more commonly __foo style tags rather than big
upper case eye sores like EFI_RUNTIME_TEXT.

Simon Glass felt quite strongly about this, so this patch converts our
existing defines over to more eye friendly ones.

x86: efi: Add EFI loader support for x86

2016-10-19T07:01:53+00:00

Add the required pieces to support the EFI loader on x86.

Since U-Boot only builds for 32-bit on x86, only a 32-bit EFI application
is supported. If a 64-bit kernel must be booted, U-Boot supports this
directly using FIT (see doc/uImage.FIT/kernel.its). U-Boot can act as a
payload for both 32-bit and 64-bit EFI.

efi: Fix missing EFIAPI specifiers

These are missing in some functions. Add them to keep things consistent.

efi_loader: Fix efi_install_configuration_table

2016-10-19T07:01:52+00:00

So far we were only installing the FDT table and didn't have space
to store any other. Hence nobody realized that our efi table allocation
was broken in that it didn't set the indicator for the number of tables
plus one.

This patch fixes it, allowing code to allocate new efi tables.

smbios: Expose in efi_loader as table

2016-10-19T07:01:52+00:00

We can pass SMBIOS easily as EFI configuration table to an EFI payload. This
patch adds enablement for that case.

While at it, we also enable SMBIOS generation for ARM systems, since they support
EFI_LOADER.

efi_loader: Expose efi_install_configuration_table

2016-10-19T07:01:51+00:00

We want to be able to add configuration table entries from our own code as
well as from EFI payload code. Export the boot service function internally
too, so that we can reuse it.

efi_loader: gop: Expose fb when 32bpp

2016-10-19T07:01:50+00:00

When we're running in 32bpp mode, expose the frame buffer address
to our payloads so that Linux efifb can pick it up.

efi_loader: Allow bouncing for network

2016-10-19T07:01:50+00:00

So far bounce buffers were only used for disk I/O, but network I/O
may suffer from the same problem.

On platforms that have problems doing DMA on high addresses, let's
also bounce outgoing network packets. Incoming ones always already
get bounced.

This patch fixes EFI PXE boot on ZynqMP for me.

efi_loader: Allow boards to implement get_time and reset_system

2016-10-18T07:08:08+00:00

EFI allows an OS to leverage firmware drivers while the OS is running. In the
generic code we so far had to stub those implementations out, because we would
need board specific knowledge about MMIO setups for it.

However, boards can easily implement those themselves. This patch provides the
framework so that a board can implement its own versions of get_time and
reset_system which would actually do something useful.

While at it we also introduce a simple way for code to reserve MMIO pointers
as runtime available.

efi_loader: Do not leak memory when unlinking a mapping

2016-10-18T07:08:08+00:00

As soon as a mapping is unlinked from the list, there are no further
references to it, so it should be freed. If it not unlinked,
update the start address and length.
