2016-10-06spl: Move spl_board_load_image() into a generic headerSimon Glass
At present this is only used on ARM and sandbox, but it is just as applicable to other architectures. Move the function prototype into the generic SPL header. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2016-09-23Remove arch/${ARCH}/include/asm/errno.hMasahiro Yamada
Unlike Linux, nothing about errno.h is arch-specific in U-Boot. As you see, all of arch/${ARCH}/include/asm/errno.h is just a wrapper of <asm-generic/errno.h>. Actually, U-Boot does not export headers to user-space, so we just have to care about the consistency in the U-Boot tree. Now all of include directives for <asm/errno.h> are gone. Deprecate <asm/errno.h>. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Alexey Brodkin <abrodkin@synopsys.com>

2016-06-19clk: convert API to match reset/mailbox styleStephen Warren
The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

2016-05-27Rename reset to sysresetStephen Warren
The current reset API implements a method to reset the entire system. In the near future, I'd like to introduce code that implements the device tree reset bindings; i.e. the equivalent of the Linux kernel's reset API. This controls resets to individual HW blocks or external chips with reset signals. It doesn't make sense to merge the two APIs into one since they have different semantic purposes. Resolve the naming conflict by renaming the existing reset API to sysreset instead, so the new reset API can be called just reset.

- Set CONFIG_SYS_CACHELINE_SIZE to ARCH_DMA_MINALIGN as that should be good enough. - Make <asm/io.h> include <asm/types.h> like other arches do - Enable many many more drivers in sandbox_defconfig so that we can get more build-time testing on this platform.

- The macro __BIGGEST_ALIGNMENT__ is gcc-specific. If it is not defined we'll just assume 16. This is correct for at least the common cases and LLVM does not provide an equivalent macro. - When linking U-Boot we're passing -T to the linker, and while gcc will just pass this along with LLVM we need to be specific.

2015-05-06sandbox: Don't try distro_bootcmd by defaultSjoerd Simons
For the distro_bootcmds to succeed on the sandbox a bit of setup is required (e.g. network configured or host image bound), so running them by default isn't that useful.

2015-04-18sandbox: eth: Add support for using the 'lo' interfaceJoe Hershberger
The 'lo' interface on Linux doesn't support thinks like ARP or link-layer access like we use to talk to a normal network interface. A higher-level network API must be used to access localhost. As written, this interface is limited to not supporting ICMP since the API doesn't allow the socket to be opened for all IP traffic and be able to receive at the same time. UDP is far more useful to test with, so it was selected over ICMP. Ping won't work, but things like TFTP should work.

SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox.
