2016-07-14tiny-printf: Support assert()Simon Glass
At present assert() is not supported with tiny-printf, so when DEBUG is enabled a build error is generated for each assert(). Add an __assert_fail() function to correct this. It prints a message and then hangs. Signed-off-by: Simon Glass <sjg@chromium.org>

As printf calls may be executed quite early, we should avoid using any BSS stored variables, since some boards put BSS in DRAM, which may not have been initialised yet.

2016-06-06efi_loader: Add DM_VIDEO supportAlexander Graf

2016-06-06efi_loader: Don't allocate from memory holesAlexander Graf
When a payload calls our memory allocator with the exact address hint, we happily allocate memory from completely unpopulated regions. Payloads however expect this to only succeed if they would be allocating from free conventional memory. This patch makes the logic behind those checks a bit more obvious and ensures that we always allocate from known good free conventional memory regions if we want to allocate ram.

2016-06-06efi_loader: Move to normal debug infrastructureAlexander Graf
We introduced special "DEBUG_EFI" defines when the efi loader support was new. After giving it a bit of thought, turns out we really didn't have to - the normal #define DEBUG infrastructure works well enough for efi loader as well. So this patch switches to the common debug() and #define DEBUG way of printing debug information. Signed-off-by: Alexander Graf <agraf@suse.de>
2016-06-06efi_loader: Add exit supportAlexander Graf

2016-06-02lib: Enable private libgcc by defaultMarek Vasut
This patch decouples U-Boot binary from the toolchain on systems where private libgcc is available. Instead of pulling in functions provided by the libgcc from the toolchain, U-Boot will use it's own set of libgcc functions. These functions are usually imported from Linux kernel, which also uses it's own libgcc functions instead of the ones provided by the toolchain. This patch solves a rather common problem. The toolchain can usually generate code for many variants of target architecture and often even different endianness. The libgcc on the other hand is usually compiled for one particular configuration and the functions provided by it may or may not be suited for use in U-Boot. This can manifest in two ways, either the U-Boot fails to compile altogether and linker will complain or, in the much worse case, the resulting U-Boot will build, but will misbehave in very subtle and hard to debug ways.

2016-05-31mmc: tegra: add basic Tegra186 supportStephen Warren
Tegra186's MMC controller needs to be explicitly identified. Add another compatible value for it. Tegra186 will use an entirely different clock/reset control mechanism to existing chips, and will use standard clock/reset APIs rather than the existing Tegra-specific custom APIs. The driver support for that isn't ready yet, so simply disable all clock/reset usage if compiling for Tegra186. This must happen at compile time rather than run-time since the custom APIs won't even be compiled in on Tegra186. In the long term, the plan would be to convert the existing custom APIs to standard APIs and get rid of the ifdefs completely. The system's main eMMC will work without any clock/reset support, since the firmware will have already initialized the controller in order to load U-Boot. Hence the driver is useful even in this apparently crippled state. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>

2016-05-27efi_loader: gop: Don't expose fb addressAlexander Graf
Recently Linux is gaining support for efifb on AArch64 and that support actually tries to make use of the frame buffer address we expose to it via gop. While this wouldn't be bad in theory, in practice it means a few bad things 1) We expose 16bit frame buffers as 32bit today 2) Linux can't deal with overlapping non-PCI regions between efifb and a different frame buffer driver For now, let's just disable exposure of the frame buffer address. Most OSs that get booted will have a native driver for the GPU anyway. Signed-off-by: Alexander Graf <agraf@suse.de> [trini: Remove line_len entirely] Signed-off-by: Tom Rini <trini@konsulko.com>
2016-05-27efi_loader: Clean up system table on exitAlexander Graf
We put the system table into our runtime services data section so that payloads may still access it after exit_boot_services.

2016-05-27efi_loader: Add bounce buffer supportAlexander Graf
Some hardware that is supported by U-Boot can not handle DMA above 32bits. For these systems, we need to come up with a way to expose the disk interface in a safe way. This patch implements EFI specific bounce buffers. For non-EFI cases, this apparently was no issue so far, since we can just define our environment variables conveniently.

To make the usage of this function more flexible, lets add the CRC start value as parameter to this function.

The new implementation is copied from the Linux version in drivers/i2c/i2c-core.c / i2c_smbus_pec(). Which supports non-zero CRC stating values.
