We load the code into NuttX heap, which can be too far from
the usual code segments for the relocation types used by the
default "small" model to reach.
This worked around out of range relocations seen with my local app.
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
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.
Some of the configuration options have changed, so update this
config file accordingly.
In this example config, the following hart configuration takes
place:
hart1: 0xafb00000 (Another NuttX)
hart2: unused
hart3: 0x80200000 (u-boot and Linux kernel)
hart4: 0x80200000 (u-boot and Linux kernel)

There is no such section. Instead, place the object mpfs_head.o at the start of
the text.
Put mpfs_head.o directly into the arch library; there is no need to define
it separately in HEAD_ASRC.

iSerialNumber field in the device descriptor can be used to determining the
board when multiple boards connected to the same host. So add feature to change
serial string by board unique ID dynamically.
To use this feature, user must be implement the board_usbdev_serialstr() logic.
refs #13909
includes following parts:
add support of sparc in arch/Kconfig
add support of sparc in boards/Kconfig
add sparc dir in arch, add sparc dir in boards
add support of sparc in libs/libc/machine
modify all the coding style problem about saprc
Add the rest of the OpenSBI code to .text.sbi -section. They belong
to there. This frees up some space in the very limited eNVM.

It’s an RP2040 based device with some interesting features:
+ small form factor (18x21.3mm)
+ 8 MByte Flash
+ RGB LED
+ Reset Button
+ USB-C
- reduced pin-header
Support in derived from: boards/arm/rp2040/raspberrypi-pico

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.
