T124/210 requires some specific configuration (VPR setup) to be performed by the bootloader before the GPU can be used. For this reason, the GPU node in the device tree is disabled by default. This patch enables the node if U-boot has performed VPR configuration. Boards enabled by this patch are T124's Jetson TK1 and Venice2 and T210's P2571.

U-boot is responsible for enabling the GPU DT node after all necessary configuration (VPR setup for T124) is performed. In order to be able to check whether this configuration has been performed right before booting the kernel, make it happen during board_init(). Also move VPR configuration into the more generic gpu.c file, which will also host other GPU-related functions, and let boards specify individually whether they need VPR setup or not.

Additionally, ARM64 devices typically run a secure monitor in EL3 and U-Boot in EL2, and set up some secure RAM carve-outs to contain the EL3 code and data. These carve-outs are located at the top of 32-bit address space. Restrict U-Boot's RAM usage to well below the location of those carve-outs. Ideally, we would the secure monitor would inform U-Boot of exactly which RAM it could use at run-time. However, I'm not sure how to do that at present (and even if such a mechanism does exist, it would likely not be generic across all forms of secure monitor).

Added 38.4MHz/48MHz entries to pll_x_table for CPU PLL. Needs to be measured - should be close to 700MHz (1.4G/2). Note that some freqs aren't in the PLLU table in T210 TRM (13, 26MHz), so I used the 12MHz table entry for them. They shouldn't be selected since they're not viable T210 OSC freqs. Since there are now 2 new OSC defines, all tables (pll_x_table, PLLU) had to increase by two entries, but since 38.4/48MHz are not viable osc freqs on T20/30/114, etc, they're just set to 0.

When U-Boot is running from EFI some of the x86 init is replaced with EFI-specific init. For example, since DRAM has already been set up, we only need to find it, not init it.

The EFI stub provides information to U-Boot in a table. This includes the memory map which is needed to decide where to relocate U-Boot. Collect this information in the early init code and store it in global_data. Fix up the BIST code at the same time since we don't have it when booting from EFI and can assume it is 0.

It is useful to be able to load U-Boot onto a board even if is it already running EFI. This can allow access to the U-Boot command interface, flexible booting options and easier development. The easiest way to do this is to build U-Boot as a binary blob and have an EFI stub copy it into RAM. Add support for this feature, targeting 32-bit initially. Also add a way to detect when U-Boot has been loaded via a stub. This goes in common.h since it needs to be widely available so that we avoid redoing initialisation that should be skipped.

On x86 the global_data pointer is provided through a somewhat-bizarre and x86-specific mechanism: the F segment register is set to a pointer to the start of global_data, so that accesses can use this build-in register. When running as an EFI application we don't want to mess with the Global Descriptor Table (GDT) and there is little advantage (in terms of code size) to doing so. Allow global_data to be a simple variable in this case. Signed-off-by: NSimon Glass <sjg@chromium.org> Reviewed-by: NBin Meng <bmeng.cn@gmail.com>
