cmd/usb_mass_storage.c: Rework ums_init() ret logic slightly

2016-04-20T17:21:24+00:00

Previously, ret could be used uninitialized if
blk_get_device_part_str() failed.  Default to ret being set to -1 so
that we always return an err up if we have a problem and then invert the
logic on testing ums_count as when that is non-zero is the time we can
return 0.

usb: ums - expose selected partition/s

2016-04-20T09:43:27+00:00

By applying this patch, it will give us some flexibility to expose
a selected partition/s.

e.g:
1. To expose several partitions
ums 0 mmc 0:1,0:6

2. To expose the all partitions
ums 0 mmc 0:0

3. To expose multiple partititions on several devices
ums 0 mmc 0:1,1:6

4. It support legacy format
ums 0 mmc 0

efi_loader: Pass fdt address directly to bootefi cmd

2016-04-18T21:11:49+00:00

The bootefi cmd today fetches its device tree pointer from either the
location appointed by "fdt addr" with a fallback to the U-Boot control
fdt.

This integration is unusual for U-Boot and diverges from the way we
usually handle parameters to boot commands. So let's pass the fdt
directly into the bootefi command instead and move the control fdt
logic into the distro boot script.

efi_loader: Put fdt into convenient location

2016-04-18T21:11:40+00:00

The uEFI spec doesn't dictate where the device tree should live at, but
legacy 32bit ARM grub2 has some assumptions that it may stay at its place
when it's already loaded by the firmware.

So let's put it somewhere where Linux that comes after would happily find
it - around the recommended 128MB line.

efi_loader: Use system fdt as fallback

2016-04-18T21:11:38+00:00

When the user did not pass any device tree or the boot script
didn't find any, let's use the system device tree as last resort
to get something the payload (Linux) may understand.

This means that on systems that use the same device tree for U-Boot
and Linux we can just share it and there's no need to manually provide
a device tree in the target image.

While at it, also copy and pad the device tree by 64kb to give us
space for modifications.

efi_loader: Increase path string to 32 characters

2016-04-18T21:11:37+00:00

Whenever we want to tell our payload about a path, we limit ourselves
to a reasonable amount of characters. So far we only passed in device
names - exceeding 16 chars was unlikely there.

However by now we also pass real file path information, so let's increase
the limit to 32 characters. That way common paths like "boot/efi/bootaa64.efi"
fit just fine.

efi_loader: Pass file path to payload

2016-04-18T21:11:36+00:00

The payload gets information on where it got loaded from. This includes
the device as well as file path.

So far we've treated both as the same thing and always gave it the device
name. However, in some situations grub2 actually wants to find its loading
path to find its configuration file.

So let's split the two semantically separte bits into separate structs and
pass the loaded file name into our payload when we load it using "load".

efi_loader: Add el torito support

2016-04-18T21:11:36+00:00

When loading an el torito image, uEFI exposes said image as a raw
block device to the payload.

Let's do the same by creating new block devices with added offsets for
the respective el torito partitions.

cmd: fdt: Use separate CMD_FDT Kconfig entry instead of OF_LIBFDT

2016-04-18T21:11:31+00:00

Create CMD_FDT Kconfig entry to have an option to disable fdt command
which is not required for small configuration which requires libfdt
only.
Enable it by default for all targets which enables OF_LIBFDT.
