6aabe229f8 riscv: define a cache line size for the generic CPU
The USB 3.0 driver xhci-mem.c requires CONFIG_SYS_CACHELINE_SIZE to be set.

Define the cache line size for QEMU on RISC-V to be 64 bytes.

28ff3f16c4 riscv: setup per-hart stack earlier
Harts need to use per-hart stack before any function call, even if that
function is a simple one. When the callee uses stack for register save/
restore, especially RA, if nested call, concurrent access by multiple
harts on the same stack will cause data-race.

This patch sets up SP before `board_init_f_alloc_reserve`. A side effect
of this is that the memory layout has changed as the following:

+----------------+        +----------------+ <----- SPL_STACK/
|  ......        |        |  hart 0 stack  |        SYS_INIT_SP_ADDR
|  malloc_base   |        +----------------+
+----------------+        |  hart 1 stack  |
|  GD            |        +----------------+ If not SMP, N=1
+----------------+        |  ......        |
|  hart 0 stack  |        +----------------+
+----------------+   ==>  |  hart N-1 stack|
|  hart 1 stack  |        +----------------+
+----------------+        |  ......        |
|  ......        |        |  malloc_base   |

7f1a30fdeb riscv: clint: Update the sifive clint ipi driver to support aclint
This RISC-V ACLINT specification [1] defines a set of memory mapped
devices which provide inter-processor interrupts (IPI) and timer
functionalities for each HART on a multi-HART RISC-V platform.

The RISC-V ACLINT specification is defined to be backward compatible
with the SiFive CLINT specification, however the device tree binding
is a new one. This change updates the sifive clint ipi driver to
support ACLINT mswi device, by checking the per-driver data field of
the ACLINT mtimer driver to determine whether a syscon based approach
needs to be taken to get the base address of the ACLINT mswi device.

4a3efd71cd riscv: Fix alignment of RELA sections in the linker scripts
In current linker script both .efi_runtime_rel and .rela.dyn sections
are of RELA type whose entry size is either 12 (RV32) or 24 (RV64).
These two are arranged as a continuous region on purpose so that the
prelink-riscv executable can fix up the PIE addresses in one loop.

However there is an 'ALIGN(8)' between these 2 sections which might
cause a gap to be inserted between these 2 sections to satisfy the
alignment requirement on RV32. This would break the assumption of
the prelink process and generate an unbootable image.

7400d34ba9 riscv: semihosting: replace inline assembly with assembly file
So far we used inline assembly to inject the actual instruction that
triggers the semihosting service. While this sounds elegant, as it's
really only about a few instructions, it has some serious downsides:
- We need some barriers in place to force the compiler to issue writes
  to a data structure before issuing the trap instruction.
- We need to convince the compiler to actually fill the structures that
  we use pointers to.
- We need a memory clobber to avoid the compiler caching the data in
  those structures, when semihosting writes data back.
- We need register arguments to make sure the function ID and the
  pointer land in the right registers.

This is all doable, but fragile and somewhat cumbersome. Since we now
have a separate function in an extra file anyway, we can do away with
all the magic and just write that in an actual assembler.
This is much more readable and robust.

The current ae350-related defconfigs could also
support newer Andes CPU IP, so modify the names of CPU
from ax25 to andesv5, and board name from ax25-ae350 to ae350.

487c211ef6 configs: ae350: Enable v5l2 cache for AE350 platforms in SPL
To reduce the code size, CONFIG_V5L2_CACHE was disabled since commit:
ca06444aac

Turing on does not significantly increase the size of u-boot-spl.bin,
so we enable it by default to improve performance.

d8a146d19b riscv: cpu: ax25: Simplify cache enabling logic in harts_early_init()
As the OpenSBI v1.2 does not enable the cache [0], we enable
the i/d-cache in harts_early_init() and do not disable in
cleanup_before_linux(). This patch also simplifies the logic
and moves the CSR encoding to include/asm/arch-andes/csr.h.
