2021-05-17riscv: Split SiFive CLINT support between SPL and U-Boot properBin Meng2-2/+3
At present there is only one Kconfig option CONFIG_SIFIVE_CLINT to control the enabling of SiFive CLINT support in both SPL (M-mode) and U-Boot proper (S-mode). So for a typical SPL config that the SiFive CLINT driver is enabled in both SPL and U-Boot proper, that means the S-mode U-Boot tries to access the memory-mapped CLINT registers directly, instead of the normal 'rdtime' instruction. This was not a problem before, as the hardware does not forbid the access from S-mode. However this becomes an issue now with OpenSBI commit 8b569803475e ("lib: utils/sys: Add CLINT memregion in the root domain") that the SiFive CLINT register space is protected by PMP for M-mode access only. U-Boot proper does not boot any more with the latest OpenSBI, that access exceptions are fired forever from U-Boot when trying to read the timer value via the SiFive CLINT driver in U-Boot. To solve this, we need to split current SiFive CLINT support between SPL and U-Boot proper, using 2 separate Kconfig options.

2020-09-30riscv: Ensure gp is NULL or points to valid dataSean Anderson1-3/+25
This ensures constructs like `if (gd & gd->...) { ... }` work when accessing the global data pointer. Without this change, it was possible for a very early trap to cause _exit_trap to directly or indirectly (through printf) to read arbitrary memory. This could cause a second trap, preventing show_regs from being printed. printf (and specifically puts) uses gd to determine what function to print with. These functions in turn use gd to find the serial device, etc. However, before accessing gd, puts first checks to see if it is non-NULL. This indicates an existing (perhaps undocumented) assumption that either gd is NULL or it is completely valid. Before this patch, gd either points to unexpected data (because it retains the value it did from the prior-stage) or points to uninitialized data (because it has not yet been initialized by board_init_f_init_reserve) until the hart has acquired available_harts_lock. This can cause two problems, depending on the value of gd->flags. If GD_FLG_SERIAL_READY is unset, then some garbage data will be printed to stdout, but there will not be a second trap. However, if GD_FLG_SERIAL_READY is set, then puts will try to print with serial_puts, which will likely cause a second trap. After this patch, gd is zero up until either a hart has set it in wait_for_gd_init, or until it is set by arch_init_gd. This prevents its usage before its data is initialized because both handle_trap and puts ensure that gd is nonzero before using it. After gd has been set, it is OK to access it because its data has been cleared (and so flags is valid). XIP cannot use locks because flash is not writable. This leaves it vulnerable to the same class of bugs regarding already-pending IPIs as before this series. Fixing that would require finding another method of synchronization, which is outside the scope of this series.

2020-09-30riscv: Rework riscv timer driver to only support S-modeSean Anderson3-3/+3
The riscv-timer driver currently serves as a shim for several riscv timer drivers. This is not too desirable because it bypasses the usual timer selection via the driver model. There is no easy way to specify an alternate timing driver, or have the tick rate depend on the cpu's configured frequency. The timer drivers also do not have device structs, and so have to rely on storing parameters in gd_t. Lastly, there is no initialization call, so driver init is done in the same function which reads the time. This can result in confusing error messages. To a user, it looks like the driver failed when trying to read the time, whereas it may have failed while initializing. This patch removes the shim functionality from the riscv-timer driver, and has it instead implement the former rdtime.c timer driver. This is because existing u-boot users who pass in a device tree (e.g. qemu) do not create a timer device for S-mode u-boot. The existing behavior of creating the riscv-timer device in the riscv cpu driver must be kept. The actual reading of the CSRs has been redone in the style of Linux's get_cycles64.

2020-07-24riscv: Make SiFive HiFive Unleashed board boot againBin Meng1-1/+1
Commit 40686c394e53 ("riscv: Clean up IPI initialization code") caused U-Boot failed to boot on SiFive HiFive Unleashed board. The codes inside arch_cpu_init_dm() may call U-Boot timer APIs before the call to riscv_init_ipi(). At that time the timer register base (e.g.: the SiFive CLINT device in this case) is unknown yet. It might be the name riscv_init_ipi() that misleads people to only consider it is related to IPI, but in fact the timer capability is provided by the same SiFive CLINT device that provides the IPI. Timer capability is needed for both UP and SMP. Considering that the original refactor does have benefits, that it makes the IPI code more similar to U-Boot initialization idioms. It also removes some quite ugly macros. Let's do the minimal revert instead of a complete revert, plus a fixes to arch_cpu_init_dm() to consider the SPL case.
