2019-04-08riscv: do not rely on hart ID passed by previous boot stageLukas Auer
RISC-V U-Boot expects the hart ID to be passed to it via register a0 by the previous boot stage. Machine mode firmware such as BBL and OpenSBI do this when starting their payload (U-Boot) in supervisor mode. If U-Boot is running in machine mode, this task must be handled by the boot ROM. Explicitly populate register a0 with the hart ID from the mhartid CSR to avoid possible problems on RISC-V processors with a boot ROM that does not handle this task.

2019-04-08riscv: add support for multi-hart systemsLukas Auer
On RISC-V, all harts boot independently. To be able to run on a multi-hart system, U-Boot must be extended with the functionality to manage all harts in the system. All harts entering U-Boot are registered in the available_harts mask stored in global data. A hart lottery system as used in the Linux kernel selects the hart U-Boot runs on. All other harts are halted. U-Boot can delegate functions to them using smp_call_function(). Every hart has a valid pointer to the global data structure and a 8KiB stack by default. The stack size is set with CONFIG_STACK_SIZE_SHIFT.

2019-04-08riscv: save hart ID in register tp instead of s0Lukas Auer
The hart ID passed by the previous boot stage is currently stored in register s0. If we divert the control flow inside a function, which is required as part of multi-hart support, the function epilog may not be called, clobbering register s0. Save the hart ID in the unallocatable register tp instead to protect the hart ID.

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: 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.

2019-03-31pico-imx7d: README: Recommend the usage of a USB hubFabio Estevam
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. The solution for that is to use an externally powered USB hub between the board and the host computer. Add such recommendation to the README file. Signed-off-by: Fabio Estevam <festevam@gmail.com>
