This PR renames `tools/Makefile.*` to have the `.mk` extension. This PR also updates `README.md` and other files that references the other files.
Note: Skipped Makefile.host for this PR since it caused failures in CI for the sim build
By using a standard extension for Makefiles (https://www.file-extension.info/format/mk), editors will auto-format files.
This change will also improve developer ergonomics when searching for specific files
Verified locally that build still works, CI will verify more!
Polarfire Icicle board has only (128K - 256) bytes for the bootloader
in the non-volatile eNVM. This space is barely enough for running NuttX.
If OpenSBI is selected, it will be placed in DDR. This all means the
nuttx.bin file grows into gigabyte size, filling the unused space (ddr -
envm) with zeroes.
The memory layout is as follows:
MEMORY
{
ddr (rx) : ORIGIN = 0x80000000, LENGTH = 4M
envm (rx) : ORIGIN = 0x20220100, LENGTH = 128K - 256
l2lim (rwx) : ORIGIN = 0x08000000, LENGTH = 1024k
l2zerodevice (rwx) : ORIGIN = 0x0A000000, LENGTH = 512k
}
OpenSBI library is used as a separate binary, which is stored into
eMMC or SD-card. It is then loaded into its precise location in DDR.
Thus, we separate OpenSBI from NuttX and end up with two images
by utilizing the objcopy options:
--only-section=sectionpattern (-j in short)
--remove-section=sectionpattern (-R in short)
This is only valid when CONFIG_MPFS_OPENSBI is set.

since VNC server is very useful even without NX:
1.Replace nxgl_coord_t with fb_coord_t
2.Replace nxgl_rect_s with fb_area_s
3.Remove nxgl_xxx function call

Summary:
- I noticed that most of nsh commands are disabled by default
due to the recent changes for CONFIG_MM_SMALL=y in apps.
- This commit re-enables some nsh commands.
Impact:
- None
Testing:
- Tested with QEMU

Some incompatibilities exist between the encryption block of the SPI
Flash peripheral and the algorithms of some file systems. LittleFS is
currently the only supported file system which is known to work
correctly when Flash Encryption is enabled.

Add a pinmap header for mpfs to be able to configure MSSIO GPIOs
This also adds Kconfigs for some different chip/package types of the PolarFire SOC

This fixes problems with DDR training sequence on aries m100pfs board
- Set LIBERO_SETTING_RPC_ODT_* to 6, which matches 40 ohm. Originally it was 120 ohm (2)
- Set BCLKSCLK_OFFSET value to 5, which matches icicle board setting

1. Fix the issue that Wi-Fi can't connect to some special routers occasionally.
2. Update Wi-Fi driver code to fix issue of failure to send pkt.
3. Replace software random with hardware random
since all NX and VNC initialization should be initiated from
user space through BOARDIOC_NX_START and BOARDIOC_VNC_START

OpenSBI may be compiled as an external library. OpenSBI commit d249d65
(Dec. 11, 2021) needs to be reverted as it causes memcpy / memcmp to
end up in the wrong section. That issue has yet no known workaround.
OpenSBI may be lauched from the hart0 (e51). It will start the U-Boot
and eventually the Linux kernel on harts 1-4.
OpenSBI, once initialized properly, will trap and handle illegal
instructions (for example, CSR time) and unaligned address accesses
among other things.
Due to size size limitations for the mpfs eNVM area where the NuttX
is located, we actually set up the OpenSBI on its own section which
is in the bottom of the DDR memory. Special care must be taken so that
the kernel doesn't override the OpenSBI. For example, the Linux device
tree may reserve some space from the beginning:
opensbi_reserved: opensbi@80000000 {
reg = <0x80000000 0x200000>;
label = "opensbi-reserved";
};
The resulting nuttx.bin file is very large, but objcopy is used to
create the final binary images for the regions (eNVM and DDR) using
the nuttx elf file.
