Add support for the Anbernic RG35XX-2024.
This device is a handheld gaming console (series) based around the Anbernic H700 SoC. It comes with 1GB of RAM and multiple face buttons for input.
Add support for the simplest model for now, and then iterate later to add board detection logic, support the entire device lineup, and move to using the mainline device tree.
Changes since V2: - Moved back to using the U-Boot specific device tree, for now. - Changed the cherry picked device tree commits to update both the U-Boot device tree and the mainline device tree, so either could be used. - Made the DRAM PHY pinconf compile time selectable instead of runtime selectable to decrease SPL memory usage.
Changes since V1: - Removed DDR3 and LPDDR3 patches from Jernej Skrabec, as they could not be tested by me and were not required to bring up this device. - Changed the default TPR6 parameter based on a suggestion from Mikhail Kalashnikov. - Cherry picked 2 commits from linux-next and converted devicetree to upstream.
