2019-04-08riscv: delay initialization of caches and debug UARTLukas Auer
Move the initialization of the caches and the debug UART until after board_init_f_init_reserve. This is in preparation for SMP support, where code prior to this point will be executed by all harts. This ensures that initialization will only be performed once on the main hart running U-Boot.

2019-04-08riscv: implement IPI platform functions using SBILukas Auer
The supervisor binary interface (SBI) provides the necessary functions to implement the platform IPI functions riscv_send_ipi() and riscv_clear_ipi(). Use it to implement them. This adds support for inter-processor interrupts (IPIs) on RISC-V CPUs running in supervisor mode. Support for machine mode is already available for CPUs that include the SiFive CLINT.

2019-04-08riscv: add infrastructure for calling functions on other hartsLukas Auer
Harts on RISC-V boot independently, U-Boot is responsible for managing them. Functions are called on other harts with smp_call_function(), which sends inter-processor interrupts (IPIs) to all other available harts. Available harts are those marked as available in the device tree and present in the available_harts mask stored in global data. The available_harts mask is used to register all harts that have entered U-Boot. Functions are specified with their address and two function arguments (argument 2 and 3). The first function argument is always the hart ID of the hart calling the function. On the other harts, the IPI interrupt handler handle_ipi() must be called on software interrupts to handle the request and call the specified function. Functions are stored in the ipi_data data structure. Every hart has its own data structure in global data. While this is not required at the moment (all harts are expected to boot Linux), this does allow future expansion, where other harts may be used for monitoring or other tasks.

In the extended text input protocol CTRL-A - CTRL-Z have to be signaled as Unicode characters a-z or A-Z depending on the shift state and not as 0x01 to 0x1a. Update Python unit test.

2019-04-07efi_loader: set image_base and image_size to correct valuesAKASHI Takahiro
Currently, image's image_base points to an address where the image was temporarily uploaded for further loading.

Since commit 9e3c0174da842 ("pico-imx7d: Add LCD support") we started to notice some hangs in U-Boot. There is not an issue on such commit per se, but due to the LCD support the current drawn is increased and this may cause issues when powering pico-imx7d-pi from USB. Some computers may be a bit strict with USB current draw and will shut down their ports if the draw is too high.
