To page mapping the lowest 2 bits needs to be 0x3. If not fix this, the final lowest 3 bits for page mapping is 0x1 which is marked as reserved. Signed-off-by: Peng Fan <peng.fan@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>

As discussed at [1], the Amlogic Meson GX SoCs can embed a BL31 firmware and a secondary BL32 firmware. Since mid-2017, the reserved memory address of the BL31 firmware was moved and grown for security reasons. But mainline U-Boot and Linux has the old address and size fixed. These SoCs have a register interface to get the two firmware reserved memory start and sizes. This patch adds a dynamic reservation of the memory zones in the device tree bootmem reserved memory zone used by the kernel in early boot. To be complete, the memory zones are also added to the EFI reserved zones. Depends on patchset "Add support for Amlogic GXL Based SBCs" at [2].

This adds platform code for the Khadas VIM board based on a Meson GXL (S905X) SoC with the Meson GXL configuration. This initial submission supports UART, MMC/SDCard and Ethernet with the Internal RMII PHY. The meson-gxl-s905x-khadas-vim.dts is synchronised from the linux 4.13 stable tree as of 4.13.8.

In the moment our exception entry code needs 34 instructions, so we can't use put it directly into the table entry, which offers "only" 32 instructions there. Right now we just put an unconditional branch there, then use a macro to place the 34 instructions *per entry* after that. That effectivly doubles the size of our exception table, which is quite a waste, given that we use it mostly for debugging purposes. Since the register saving part is actually identical, let's just convert that macro into a function, and "bl" into it directly from the exception slot, of course after having saved at least the original LR. This saves us about 950 bytes of code, which is quite a relief for some tight SPLs, in particular the 64-bit Allwinner ones. Signed-off-by: Andre Przywara <andre.przywara@arm.com>
