297d48857a board: lx2160a: Correct board fixup for PCIe nodes
Update "board_fix_fdt" with correct counter value "i".
This will fix the issue while fetching the "reg_names"
resource from fdt after fixup.

c463eeb4b6 ls1021a: Set CONFIG_SYS_BOOTMAPSZ to the memory for relocation
This patch sets CONFIG_SYS_BOOTMAPSZ to the amount of memory available
to safely contain a kernel, device tree and initrd for relocation. The
way to set fdt_high as 0xffffffff to disable device tree relocation is

fef907b2e4 efi_loader: create reservations after ft_board_setup
Some memory reservations are made in ft_board_setup(). Ensure that we
create reserved memory map entries after ft_board_setup().

The downside of this patch is that if bootefi is called multiple times with
an devicetree argument superfluous reservations for the old copies of the
device tree will exist. But that is still better than missing a reservation.

Deleting the superfluous reservations is not possible because reservations
in the memory map are rounded to page size and may be coallesced.

1e32715602 riscv: Add SBI v0.2 extension definitions
Few v0.1 SBI calls are being replaced by new SBI calls that follows
v0.2 calling convention.

This patch just defines these new extensions.

f58fc34a2b riscv: Add basic support for SBI v0.2
The SBI v0.2 introduces a base extension which is backward compatible
with v0.1. Implement all helper functions and minimum required SBI
calls from v0.2 for now. All other base extension function will be
added later as per need.

As v0.2 calling convention is backward compatible with v0.1, remove
the v0.1 helper functions and just use v0.2 calling convention.

Add a new Kconfig options CONFIG_SBI for the new SBI v0.2 codes, and
let CONFIG_SBI_IPI depend on it.

215c3a7701 riscv: Mark existing SBI as v0.1 SBI
As per the new SBI specification, current SBI implementation version
is defined as 0.1 and will be removed/replaced in future. Each of the
function call in 0.1 is defined as a separate extension which makes
easier to replace them one at a time.

Rename existing implementation to reflect that. This patch is just
a preparatory patch for SBI v0.2 and doesn't introduce any functional
changes.

f295e00c61 riscv: Avoid calling sbi_clear_ipi()
There is no need for S-mode U-Boot to call sbi_clear_ipi() as it
can be cleared directly from S-mode. This saves some cycles.

fe13692e23 riscv: Fix sbi_remote_sfence_vma{,_asid}
Currently sbi_remote_sfence_vma{,_asid} does not pass their arguments
to SBI at all, which is semantically incorrect.

This keeps in sync with Linux kernel commit:

6d8eae9ab7 watchdog: Handle timer wrap around
On some platforms/architectures the value from get_timer() can wrap.
This is particularly problematic when long-running code needs to measure
a time difference as is the case with watchdog_reset() which tries to
avoid tickling the watchdog too frequently.

Use time_after() from time.h instead of a plain > comparison to avoid
any issues with the time wrapping on a system that has been sitting in
u-boot for a long time.

ed666fb129 watchdog: Use dev_read only if OF_PLATDATA is not enabled
Currently watchdog tries to use dev_read_u32_default to get timeout
configuration in case OF_CONTROL is enabled. However, if SPL is
built with OF_PLATDATA this has no sense as there is no device tree.

This patch fixes this issue by only use dev_read_u32_default if OF_CONTROL
is enabled but OF_PLATDATA is not.
