The image must be placed into:
boards/risc-v/mpfs/icicle/include/boot_romfsimg.h
The image is mounted by mpfs_bringup, which is run by the application
itself, or by board_late_initialize() in the case when
CONFIG_BOARD_LATE_INITIALIZE is defined, e.g. with CONFIG_BUILD_KERNEL
- Add test for mode support, which is architecture dependent
- Add tests for address alignment and region size
- Add option to query for access rights
- The function goes through every PMP entry and tests if an address
range from [base, base+size] has been configured for desired
access rights.
- If several PMP entries match the range and access rights, the
information is combined
- End result is either no access, a partial match was found, or a full
match was found. Details about the partial match are not provided.
The intent for testing access rights and not just blindly applying them
is a case where they are already set in e.g. a bootloader. In this
case, nothing should be done, unless the configuration does not match,
in which case the software must not continue further.
NOTE: THIS ONLY WORKS WHEN KERNEL RUNS IN M-MODE FOR NOW
This frees the PMP for other use, e.g. HART memory separation.
The page tables are statically allocated, 1 per level.
This feature is now behind CONFIG_MPFS_USE_MMU_AS_MPU, because
only the MPFS target supports this (others are not tested).
If the MMU is used for memory separation within a HART, the PMP must
still be configured to allow user access to the memory mapped for the
HART, because PMP *rekoves* access by default. At this point all of
the user memory as well as the kernel RAM are opened.
A more flexible solution for PMP configuration will follow.
The old implementation used the default ld.script for the kernel side
which did not obey the memory.ld limits whatsoever.
Also, provide the user space addresses from the linker script to get rid
of the pre-processor macros that define (incorrect) default values for
the user space composition.

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.

For FAT the same buffer is used for read and writes, there
is a possibility a cache line is dirty. But the fs is
not dirty and will not write the sector to disk. This can
be seen https://github.com/PX4/NuttX/pull/175
When the system is busy that cache line can be evicted after the
RX DMA has completed and overwrite the data in memory. The solution
is to invalidate before the DMA to prevent an evection causing an
overwite, and after the DMA it to insure coherency.
According to Make documentation:
- "Commas and unmatched parentheses or braces cannot appear in the text
of an argument as written";
- "Leading spaces cannot appear in the text of the first argument as
written".
Although in the current state it was not resulting in parsing issues, it
