fdt: add memory bank decoding functions for board setup

2016-12-20T08:15:28+00:00

Add two functions for use by board implementations to decode the memory
banks of the /memory node so as to populate the global data with
ram_size and board info for memory banks.

The fdtdec_setup_memory_size() function decodes the first memory bank
and sets up the gd->ram_size with the size of the memory bank. This
function should be called from the boards dram_init().

The fdtdec_setup_memory_banksize() function decode the memory banks
(up to the CONFIG_NR_DRAM_BANKS) and populates the base address and size
into the gd->bd->bi_dram array of banks. This function should be called
from the boards dram_init_banksize().

efi_loader: Allow to compile helloworld.efi w/o bundling it

2016-11-27T14:53:39+00:00

Today we can compile a self-contained hello world efi test binary that
allows us to quickly verify whether the EFI loader framwork works.

We can use that binary outside of the self-contained test case though,
by providing it to a to-be-tested system via tftp.

This patch separates compilation of the helloworld.efi file from
including it in the u-boot binary for "bootefi hello". It also modifies
the efi_loader test case to enable travis to pick up the compiled file.
Because we're now no longer bloating the resulting u-boot binary, we
can enable compilation always, giving us good travis test coverage.

image: Combine image_sig_algo with image_sign_info

2016-11-21T19:07:31+00:00

Remove the need to explicitly add SHA/RSA pairings. Invalid SHA/RSA
pairings will still fail on verify operations when the hash length is
longer than the key length.

Follow the same naming scheme "checksum,crytpo" without explicitly
defining the string.

Indirectly adds support for "sha1,rsa4096" signing/verification.

2016-11-21T19:07:31+00:00

Cut down on the repetition of algorithm information by defining separate
checksum and crypto structs. image_sig_algos are now simply pairs of
unique checksum and crypto algos.

rsa: Verify RSA padding programatically

2016-11-21T19:07:30+00:00

Padding verification was done against static SHA/RSA pair arrays which
take up a lot of static memory, are mostly 0xff, and cannot be reused
for additional SHA/RSA pairings. The padding can be easily computed
according to PKCS#1v2.1 as:

  EM = 0x00 || 0x01 || PS || 0x00 || T

where PS is (emLen - tLen - 3) octets of 0xff and T is DER encoding
of the hash.

Store DER prefix in checksum_algo and create rsa_verify_padding
function to handle verification of a message for any SHA/RSA pairing.

rsa: cosmetic: rename pad_len to key_len

2016-11-21T19:07:30+00:00

checksum_algo's pad_len field isn't actually used to store the length of
the padding but the total length of the RSA key (msg_len + pad_len)

ls2080: Exit dpaa only right before exiting U-Boot

2016-11-17T13:18:55+00:00

On ls2080 we have a separate network fabric component which we need to
shut down before we enter Linux (or any other OS). Along with that also
comes configuration of the fabric using a description file.

Today we always stop and configure the fabric in the boot script and
(again) exit it on device tree generation. This works ok for the normal
booti case, but with bootefi the payload we're running may still want to
access the network.

So let's add a new fsl_mc command that defers configuration and stopping
the hardware to when we actually exit U-Boot, so that we can still use
the fabric from an EFI payload.

For existing boot scripts, nothing should change with this patch.

x86: Enable EFI loader support

2016-11-14T22:24:04+00:00

Enable this so that EFI applications (notably grub) can be run under U-Boot
on x86 platforms.

At present the 'hello world' EFI application is not supported for the
qemu-x86_efi_payload64 board. That board builds a payload consisting of a
64-bit header and a 32-bit U-Boot, which is incompatible with the way the
EFI loader builds its EFI application. The following error is obtained:

x86_64-linux-ld.bfd: i386 architecture of input file
   `lib/efi_loader/helloworld.o' is incompatible with i386:x86-64 output

This could be corrected with additional Makefile rules. For now, this
feature is disabled for that board.

efi: Add support for a hello world test program

2016-11-14T22:24:03+00:00

It is useful to have a basic sanity check for EFI loader support. Add a
