Patch queue for efi - 2018-01-23

This time around we have a lot of EFI patches from Heinrich.
Highlights are:

  - Allow EFI applications to register as drivers
  - Allow exposure of U-Boot block devices from an EFI payload
  - Compatibility improvements

efi_driver: EFI block driver

2018-01-22T22:09:14+00:00

This patch provides
* a uclass for EFI drivers
* a EFI driver for block devices

For each EFI driver the uclass
* creates a handle
* adds the driver binding protocol

The uclass provides the bind, start, and stop entry points for the driver
binding protocol.

In bind() and stop() it checks if the controller implements the protocol
supported by the EFI driver. In the start() function it calls the bind()
function of the EFI driver. In the stop() function it destroys the child
controllers.

The EFI block driver binds to controllers implementing the block io
protocol.

When the bind function of the EFI block driver is called it creates a
new U-Boot block device. It installs child handles for all partitions and
installs the simple file protocol on these.

The read and write functions of the EFI block driver delegate calls to the
controller that it is bound to.

A usage example is as following:

U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and
exposes a handle with the block IO protocol. It calls ConnectController.

Now the EFI block driver installs the partitions with the simple file
protocol.

iPXE uses the simple file protocol to load Grub or the Linux Kernel.

env: ENV_IS_IN_FAT improvements

2018-01-22T21:43:31+00:00

Make it select FS_FAT as well, because if it's not selected, enabling
ENV_IS_IN_FAT causes a Kconfig warning:

warning: (ENV_IS_IN_FAT) selects FAT_WRITE which has unmet direct dependencies (FS_FAT)

This also allows dropping some code from config_fallbacks.

Also drop the unnecessary help text about having to enable
CONFIG_FAT_WRITE - Kconfig automatically handles that.

fs: Migrate ext4 to Kconfig

2018-01-22T21:43:30+00:00

Migrate the following symbols to Kconfig:

CONFIG_FS_EXT4
CONFIG_EXT4_WRITE

The definitions in config_fallbacks.h can now be expressed in Kconfig.

vsprintf.c: add GUID printing

2017-09-12T21:58:00+00:00

This works (roughly) the same way as linux's, but we currently always
print lower-case (ie. we just keep %pUB and %pUL for compat with linux),
mostly just because that is what uuid_bin_to_str() supports.

  %pUb:   01020304-0506-0708-090a-0b0c0d0e0f10
  %pUl:   04030201-0605-0807-090a-0b0c0d0e0f10

It will be used by a later efi_loader paths for efi variables and for
device-path-to-text protocol, and also quite useful for debug prints
of protocol GUIDs.

include/config_fallbacks.h: add default for CONFIG_SYS_MAXARGS

2017-09-03T19:30:29+00:00

CONFIG_SYS_MAXARGS contains the maximum number of arguments accepted
by U-Boot commands. Since the vast majority of the platforms define it
to 16, it makes sense to have a default definition to 16, which will
allow to remove this definition from a significant number of
platforms.

It will allow to remove the default definition from 216 platform .h
files, leaving only 56 platforms with non-default values (15, 24, 32,
48, 64, 96, 128 or 256).

include/config_fallbacks.h: change fallback for CONFIG_SYS_PBSIZE

2017-09-03T19:30:27+00:00

Most of the platforms are using CONFIG_SYS_CBSIZE +
sizeof(CONFIG_SYS_PROMPT) + 16 as their value for CONFIG_SYS_PBSIZE,
so let's adopt this for the fallback value of CONFIG_SYS_PBSIZE.

This will allow us to drop an explicit definition of CONFIG_SYS_PBSIZE
from a large number of platforms.

include/config_fallbacks.h: add default for CONFIG_SYS_CBSIZE

2017-09-03T15:04:52+00:00

CONFIG_SYS_CBSIZE contains the buffer size for input for the
console. The vast majority of platforms define them to some reasonable
value (256, 512 or 1024 bytes), and it is quite annoying to repeat
this definition for all platforms while it isn't really HW-related.

Therefore, let's provide a sane fallback value in config_fallbacks.h,
so that platforms can rely on it instead of having to explicitly
define it.

We use 1024 when KGDB is enabled, and 256 otherwise, which is what the
majority of the platforms are doing.

nvme: Adjust the 'nvme' command to use blk_common_cmd()

env: Migrate CONFIG_ENV_IS_IN_FAT options to Kconfig

2017-07-31T15:22:56+00:00

We rename the various FAT_ENV_xxx options to CONFIG_ENV_FAT_xxx so that
they can be modified via Kconfig.  Migrate all existing users to the new
values.
