2018-01-12Makefile: ensure DTB doesn't overflow into initial stackStephen Warren
With CONFIG_SYS_INIT_SP_BSS_OFFSET enabled, the initial (pre-relocation) stack is placed some distance after bss_start. The control DTB is appended to the U-Boot binary at bss_start. If the DTB is too large, or the SP BSS offset too small, then the initial stack could corrupt the DTB. Enhance the Makefile to check whether this is likely to occur.

2018-01-12ARM: Tegra186: calculate load addresses at bootStephen Warren
In the presence of potentially fragemented memory, we cannot hard-code addresses into environment variables such as kernel_addr_r. Instead, we must calculate those addresses at run-time based on available memory locations. Implement the code to perform such runtime calculation, based on requirements described in environment variables, to allow the user full control over the allocation.

2018-01-12ARM: Tegra186: don't map memory not in RAM banksStephen Warren
Tegra186 currently restricts its DRAM usage to entries in the /memory node in the DTB passed to it. However, the MMU configuration always maps the entire first 2GB of RAM. This could allow the CPU to speculatively access RAM that isn't part of the in-use banks. This patch switches to runtime construction of the table that's used to construct the MMU translation tables, and thus prevents access to RAM that's not part of a valid bank. Note: This patch is intended to prevent access to RAM regions which U-Boot does not need to access, with the primary purpose of avoiding theoretical speculative access to physical regions for which the HW will throw errors (e.g. carve-outs that the CPU has no permission to access at a bus level, bad ECC pages, etc.). In particular, this patch is not deliberately related to the speculation-related security issues that were recently announced. The apparent similarity is a coincidence.

2018-01-12ARM: Tegra186: search for best RAM bankStephen Warren
In the future, the list of DRAM regions passed to U-Boot in the DTB may be quite long and fragmented. Due to this, U-Boot must search through the regions to find the best region to relocate into, rather than relying on the current assumption that the top of bank 0 is a reasonable relocation target. This change implements such searching. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2018-01-12ARM: bootm: don't assume sp is in DRAM bank 0Stephen Warren
arch_lmb_reserve() currently assumes that the stack pointer is within DRAM bank 0. This is not necessarily true.

2018-01-12ARMv8: add optional Linux kernel image headerStephen Warren
Allow placing a Linux kernel image header at the start of the U-Boot binary. This is useful since the image header reports the amount of memory (BSS and similar) that U-Boot needs to use, but that isn't part of the binary size. This can be used by the code that loads U-Boot into memory to determine where to load U-Boot, based on other users of memory.

Enable CONFIG_SYS_INIT_SP_BSS_OFFSET for all 64-bit Tegra boards. Place the stack/... 512KiB from the end of the U-Boot binary. This should be plenty to accommodate the current DTBs (max 64 KiB), early malloc region (6KiB), stack usage, and plenty of slack, while still not placing it too far away from the U-Boot binary.

2018-01-12ARMv8: Allow dynamic early stack pointerStephen Warren
U-Boot typically uses a hard-coded value for the stack pointer before relocation. Implement option SYS_INIT_SP_BSS_OFFSET to instead calculate the initial SP at run-time. This is useful to avoid hard-coding addresses into U-Boot, so that can be loaded and executed at arbitrary addresses and thus avoid using arbitrary addresses at runtime. This option's value is the offset added to &_bss_start in order to calculate the stack pointer. This offset should be large enough so that the early malloc region, global data (gd), and early stack usage do not overlap any appended DTB.

2018-01-12ARM: imx: cm_fx6: env: try to determine dtb to useChristopher Spinrath
Some distributions like Fedora expect U-Boot to select a proper devicetree. Since there are several variants of the cm-fx6 module featuring different SoC variants and the module can be paired with several baseboards, it is not viable to hardcode a filename. Instead, follow the lead of other i.MX6 based devices and try to determine the devicetree to use with the help of the board name and the SoC variant exported by the board code, before calling the distro bootcommand. For now, only for the Utilite Pro a proper devicetree filename is known but further variants of the Utilite Computer or other devices based on the cm-fx6 module may be added in the future.

2018-01-12ARM: imx: cm_fx6: export board and soc info to envChristopher Spinrath
Like many other i.MX6 based boards, there are multiple variants of the cm-fx6 module featuring different SoC variants. Furthermore, the module can be paired with multiple baseboards. At the same time modern distribution like Fedora require U-Boot to select a proper devicetree which depends on the SoC variant and the baseboard. Thus, export the SoC variant and the actual board to the environment following the conventions of other i.MX6 devices (e.g. the NXP boards) such that the environment can select a devicetree file to load. For now, we only know for sure that the cm-fx6 module and the SB-fx6m baseboard amount to a Utilite Computer variant (depending on the SoC). Further combinations may be added in the future; e.g. CompuLab's evaluation board once someone can verify the identification string stored in its eeprom.
