- Update qemu-riscv.rst build instructions.
- Add support for SPI on Kendryte K210.
- Add Microchip PolarFire SoC Icicle Kit support.
- Add support for an early timer.

This patch adds Microchip MPFS Icicle Kit support. For now, only
NS16550 Serial, Microchip clock, Cadence eMMC and MACB drivers are
enabled. The Microchip MPFS Icicle defconfig by default builds
U-Boot for S-Mode because U-Boot on Microchip PolarFire SoC will run
in S-Mode as payload of HSS + OpenSBI.

This enables configs necessary for using SPI. The environment is saved to
the very end of SPI flash. This is unlikely to be overwritten unless the
entire flash is reprogrammed.
This also supplies a default bootcommand. It loads an image and device tree
from the first partition of the MMC. This is a minimal/least effort
bootcmd, so suggestions (especially in the form of patches) are welcome. I
didn't set up distro boot because I think it is unlikely that any
general-purpose linux distros will ever be ported to this board.

When setting aside a GPT partition for holding the U-Boot environment,
having a partition type GUID [1] indicating "Linux filesystem" (as
most tools default to) is somewhat misleading - and there's no other
well-known type GUID that is better suited. So to have a canonical
value to put into the type field, define
3de21764-95bd-54bd-a5c3-4abe786f38a8
to mean a partition holding a U-Boot environment.
This is a v5 namespace-name GUID [2], generated [3] from a namespace
of "25cbcde0-8642-47c6-a298-1a3a57cd256b" and name "U-Boot
environment".
Should future type GUIDs be defined in the context of U-Boot, it's
sensible to use that same namespace GUID.

The __of_translate_address routine translates an address from the
device tree into a CPU physical address. A note in the description of
the routine explains that the crossing of any level with
since inherited from IBM. This does not happen for Texas Instruments, or
at least for the beaglebone device tree. Without this patch, in fact,
the translation into physical addresses of the registers contained in the
am33xx-clocks.dtsi nodes would not be possible. They all have a parent
with #size-cells = <0>.
The CONFIG_OF_TRANSLATE_ZERO_SIZE_CELLS symbol makes translation
possible even in the case of crossing levels with #size-cells = <0>.
The patch acts conservatively on address translation, except for
removing a check within the of_translate_one function in the
drivers/core/of_addr.c file:
+
ranges = of_get_property(parent, rprop, &rlen);
- if (ranges == NULL && !of_empty_ranges_quirk(parent)) {
- debug("no ranges; cannot translate\n");
- return 1;
- }
if (ranges == NULL || rlen == 0) {
offset = of_read_number(addr, na);
memset(addr, 0, pna * 4);
debug("empty ranges; 1:1 translation\n");
There are two reasons:
1 The function of_empty_ranges_quirk always returns false, invalidating
the following if statement in case of null ranges. Therefore one of
the two checks is useless.
2 The implementation of the of_translate_one function found in the
common/fdt_support.c file has removed this check while keeping the one
about the 1:1 translation.
The patch adds a test and modifies a check for the correctness of an
address in the case of enabling translation also for zero size cells.
The added test checks translations of addresses generated by nodes of
a device tree similar to those you can find in the files am33xx.dtsi
and am33xx-clocks.dtsi for which the patch was created.
The patch was also tested on a beaglebone black board. The addresses
generated for the registers of the loaded drivers are those specified
by the AM335x reference manual.
