2017-05-22lib: move hash CONFIG options to KconfigTom Rini
Commit 94e3c8c4fd7b ("crypto/fsl - Add progressive hashing support using hardware acceleration.") created entries for CONFIG_SHA1, CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and CONFIG_SHA_PROG_HW_ACCEL. However, no defconfig has migrated to it. Complete the move by first adding additional logic to various Kconfig files to select this when required and then use the moveconfig tool. In many cases we can select these because they are required to implement other drivers. We also correct how we include the various hashing algorithms in SPL. This commit was generated as follows (after Kconfig additions): [1] tools/moveconfig.py -y SHA1 SHA256 SHA_HW_ACCEL [2] tools/moveconfig.py -y SHA_PROG_HW_ACCEL Note: We cannot move SHA_HW_ACCEL and SHA_PROG_HW_ACCEL simultaneously because there is dependency between them.

2017-05-09Allow boards to initialize the DT at runtime.Alex Deymo
In some boards like the Raspberry Pi the initial bootloader will pass a DT to the kernel. When using U-Boot as such kernel, the board code in U-Boot should be able to provide U-Boot with this, already assembled device tree blob. This patch introduces a new config option CONFIG_OF_BOARD to use instead of CONFIG_OF_EMBED or CONFIG_OF_SEPARATE which will initialize the DT from a board-specific funtion instead of bundling one with U-Boot or as a separated file. This allows boards like the Raspberry Pi to reuse the device tree passed from the bootcode.bin and start.elf firmware files, including the run-time selected device tree overlays.

2017-04-13tiny-printf: Add support for %p formatVignesh R
Add support for %p, %pa[p], %pM, %pm and %pI4 formats to tiny-printf. %pM and %pI4 are widely used by SPL networking stack and is required if networking support is desired in SPL. %p, %pa and %pap are mostly used by debug prints and hence supported only when DEBUG is enabled. Before this patch: $ size spl/u-boot-spl text data bss dec hex filename 99325 4899 218584 322808 4ecf8 spl/u-boot-spl After this patch (with CONFIG_SPL_NET_SUPPORT): $ size spl/u-boot-spl text data bss dec hex filename 99666 4899 218584 323149 4ee4d spl/u-boot-spl So, this patch adds ~350 bytes to code size. If CONFIG_SPL_NET_SUPPORT is not enabled, this adds ~25 bytes.

2017-03-26tpm: Add function to load keys via their parent's SHA1 hashmario.six@gdsys.cc
If we want to load a key into a TPM, we need to know the designated parent key's handle, so that the TPM is able to insert the key at the correct place in the key hierarchy. However, if we want to load a key whose designated parent key we also previously loaded ourselves, we first need to memorize this parent key's handle (since the handles for the key are chosen at random when they are inserted into the TPM). If we are, however, unable to do so, for example if the parent key is loaded into the TPM during production, and its child key during the actual boot, we must find a different mechanism to identify the parent key. To solve this problem, we add a function that allows U-Boot to load a key into the TPM using their designated parent key's SHA1 hash, and the corresponding auth data.

2017-01-13libfdt: Correct fdt handling of overlays without fixups and base trees ↵David Gibson
without symbols The fdt_overlay_apply() function purports to support the edge cases where an overlay has no fixups to be applied, or a base tree which has no symbols (the latter can only work if the former is also true). However it gets it wrong in a couple of small ways: * In the no fixups case, it doesn't fail immediately, but will attempt fdt_for_each_property_offset() giving -FDT_ERR_NOTFOUND as the node offset, which will fail. Instead it should succeed immediately, since there's nothing to do. * In the case of no symbols, it again doesn't fail immediately. However if there is an actual fixup it will fail with an unexpected error, because -FDT_ERR_NOTFOUND is passed to fdt_getprop() when attempting to look up the symbols. We should instead return -FDT_ERR_NOTFOUND directly. Both of these errors lead to the code returning misleading error codes in failing cases.

On ls2080 we have a separate network fabric component which we need to shut down before we enter Linux (or any other OS).

This works ok for the normal booti case, but with bootefi the payload we're running may still want to access the network.
