Changes: - Kernel patches updated for the 5.10.41 linux-renesas kernel, most changes are for the upstream rename of the non-engineering sample H3 from r8a7795 to r8a77951. - The kernel patches have been renamed to match git format-patch / devtool naming conventions to be a bit more consistent and hopefully simplify future updates. - To maintain consistency with the other rcar3 boards, as part of the kernel patch updates the reference hardware devicetree has been renamed to r8a77951-agl-refhw, which does result in a user visible change in the .dtb name. - The upstreamed, then reverted upstream patch to arm-trusted-firmware to disable FDT generation has been replaced with a simpler patch to just put "renesas,unknown" in the compatible string instead of panic-ing. This should be easier to carry forward. - Documentation updated for new branch & tag.

2021-10-26arm-trusted-firmware: build 1rank firmware when MACHINE=agl-refhw-h3Scott Murray1-1/+1
Tweak the arm-trusted-firmware bbappend to build the extra 1rank firmware when building standalone with MACHINE=agl-refhw-h3, and also add an anonymous python snippet to disable the default firmware configurations from the base recipe in that situation as well, as they are not useful.

2021-10-20Add support for 16Gbit/1rank DRAM version of the AGL reference hardwareYoshiki Ito1-0/+3
The AGL reference hardware which is numbered 100 or above has 16Gbit/1rank DRAM. If you use the reference hardware described above, please flash the firmware with the suffix "-agl-refhw-4x2g-1rank".

2021-06-30arm-trusted-firmware: Enable building in AGL buildScott Murray1-137/+177
Leverage the reworked extra_opl_ipt hook in the rcar3 BSP's arm-trusted-firmware recipe as of BSP v4.7.0 to enable building the reference hardware flavor of the firmware as an extra firmware version when building with MACHINE=h3ulcb. This will then enable working inside the AGL build which combines the reference hardware support into its h3ulcb build to avoid needing an extra platform build. Support for building standalone with MACHINE=agl-refhw-h3 has been retained for potential use outside of the full AGL build. The firmware documentation has been reworked to document the build and flashing procedure for both types of build. Based on initial prototype by Vasyl Vavrychuk at: https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl-refhw/+/26352 Bug-AGL: SPEC-3916 Signed-off-by: Scott Murray <scott.murray@konsulko.com> Change-Id: I5f74450851aeb4cb015a21e234709eca2014f378
2020-10-26Update firmware documentationScott Murray1-8/+8
Changes: - Add missing "optee-os" to bitbake command line for building the required firmware. - Reorganize the firmware table to have the columns in the order that the information is needed for the EM_W commands. Bug-AGL: SPEC-3658 Signed-off-by: Scott Murray <scott.murray@konsulko.com>
2020-10-21Rework for AGL UCB integrationScott Murray1-4/+54
Changes include: - The provided kernel patches have been reworked to not modify the salvator-x(s) devicetree source, but to introduce new files for the reference hardware instead. There is some possibility that the reference hardware devicetree could be based off the the salvator-x with some work and perhaps splitting of the salvator-x source, but for now the aim is to avoid breaking the salvator-x(s) with the reference hardware changes. - The modifications to the r8a7795 pinctrl driver have been replaced with a splitting of the USB interface OVC pins into their own pin groups, which has previously been done for other older Renesas hardware. This allows booting the reference hardware off of the same kernel as other H3 boards, at the expense of minor devicetree modifications for them (e.g. h3ulcb). There is likely some more work required if this needs to be upstreamed, as the ulcb.dtsi changes would mean that the pinctrl drivers for M3 would also need the new pin groups. - All changes for the ST asm330lhh driver addtion have been moved to that patch to the kernel. - A machine conf file has been added for "agl-refhw-h3", and the firmware documentation updated to document how to set up a build of the firmware using it. This is required due to the firmware options from this layer's arm-trusted-firmware bbappend not being compatible with other H3 boards (eMMC versus Hyperflash boot). A definition of the COMPATIBLE_MACHINE variable has been added to that bbappend to make sure that attempting to use it with another H3 machine will trigger an error. In AGL, the bbappend will need to be masked out with BBMASK for now. - The top-level README file has been updated to reflect the expected integration in AGL.

2020-10-20Initial check-inScott Murray1-0/+161
Initial check-in of the contents of the meta-refhw directory from the AGL_Refhw_sample_software_20200512.tar.gz archive provided by Panasonic as the initial BSP for the AGL reference hardware. The only change from the files as provided is that unneeded execute file permissions have been removed. Bug-AGL: SPEC-3658 Signed-off-by: Scott Murray <scott.murray@konsulko.com>
