2020-02-10riscv: Fix breakage caused by linker relaxationSean Anderson
Due to the two-instruction sequence needed to access arbitrary memory locations, the RISC-V linker aggressively optimises memory accesses and jumps at link-time. This is called "linker relaxation," and is discussed in this SiFive article <https://www.sifive.com/blog/all-aboard-part-3-linker-relaxation-in-riscv-toolchain>. One of the optimizations in place is to assume that the __global_pointer symbol is placed in the gp register. To quote the article: "...The magic __global_pointer$ symbol is defined to point 0x800 bytes past the start of the .sdata section. The 0x800 magic number allows signed 12-bit offsets from __global_pointer$ to address symbols at the start of the .sdata section. The linker assumes that if this symbol is defined, then the gp register contains that value, which it can then use to relax accesses to global symbols within that 12-bit range. The compiler treats the gp register as a constant so it doesn't need to be saved or restored, which means it is generally only written by _start, the ELF entry point." However, U-Boot instead keeps the global data pointer in gp. This causes memory accesses and jumps optimized to use the gp pointer to fail. To fix this problem, we undefine the __global_pointer symbol. Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Rick Chen <rick@andestech.com>

2020-02-07dm: irq: Add support for requesting interruptsSimon Glass
At present driver model supports the IRQ uclass but there is no way to request a particular interrupt for a driver. Add a mechanism, similar to clock and reset, to read the interrupts required by a device from the device tree and to request those interrupts. U-Boot itself does not have interrupt-driven handlers, so just provide a means to read and clear an interrupt. This can be useful to handle peripherals which must use an interrupt to determine when data is available, for example. Bring over the basic binding file as well, from Linux v5.4. Note that the older binding is not supported in U-Boot; the newer 'special form' must be used. Add a simple test of the new functionality.

2020-02-07dm: irq: Add support for interrupt controller typesSimon Glass
There can be different types of interrupt controllers in a system and some drivers may need to distinguish between these. In general this can be handled using the device tree by adding the interrupt information to device nodes. However on x86 devices we have interrupt controllers which are not tied to any particular device and not really used in U-Boot. These still need to be inited, so a convenient method is to give each controller a type and allow a particular controller type to be probed. Add support for this in sandbox along with a test.

2020-02-07x86: apl: Drop the I2C config in FSP-SSimon Glass
This config is not actually used here and in U-Boot it seems better to set this using the device tree for each individual controller. The monolithic config of the FSP-S is only necessary if the FSP is actually configuring something, but here it is not. The FSP-S does enable/disable the various I2C ports. It might be nice to handle this using the okay/disabled property of each port, but that can be considered later.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.
