Add support for coral which is a range of apollolake-based Chromebook released in 2017. This also includes reef released in 2016, since it is based on the same SoC.
Signed-off-by: Simon Glass sjg@chromium.org ---
Changes in v3: - Ad FSP-S support - Add CONFIG_TPL_X86_ASSUME_CPUID to reduce code size - Add Chrome OS EC support - Add a proper SPI node and make the SPI flash node a child - Add bootstage support - Add more documentation - Add spi alias in device tree - Disable the bootcommand since it does nothing useful on coral - Don't enable SPI flash in TPL by default - Drop CONFIG_SPL_NET_SUPPORT - Drop patch '86: timer: Reduce timer code size in TPL on Intel CPUs' - Drop patch 'dm: core: Don't include ofnode functions with of-platdata' - Drop patch 'spi: sandbox: Add a test driver for sandbox SPI flash' - Drop patch 'spl: Allow SPL/TPL to use of-platdata without libfdt' - Drop patch 'x86: apollolake: Add definitions for the Intel Fast SPI interface' - Drop patch 'x86: timer: Set up the timer in timer_early_get_count()' - Enable video and USB3 - Reduce amount of early-pad data in TPL - Tidy up the pad settings in the device tree - Use a zero-based tsc timer

SPDX-License-Identifier: GPL-2.0+ +.. sectionauthor:: Simon Glass sjg@chromium.org + +Chromebook Coral +================ + +Coral is a Chromebook (or really about 20 different Chromebooks) which use the +Intel Apollolake platform (APL). The 'reef' Chromebooks use the same APL SoC so +should also work. Some later ones based on Glacier Lake (GLK) need various +changes in GPIOs, etc. but are very similar. + +It is hoped that this port can enable ports to embedded APL boards which are +starting to appear. + +Note that booting U-Boot on APL is already supported by coreboot and +Slim Bootloader. This documentation refers to a 'bare metal' port. + + +Boot flow - TPL +--------------- + +Apollolake boots via an IFWI (Integrated Firmware Image). TPL is placed in this, +in the IBBL entry. + +On boot, an on-chip microcontroller called the CSE (Converged Security Engine) +sets up some SDRAM at ffff8000 and loads the TPL image to that address. The +SRAM extends up to the top of 32-bit address space, but the last 2KB is the +start16 region, so the TPL image must be 30KB at most, and CONFIG_TPL_TEXT_BASE +must be ffff8000. Actually the start16 region is small and it could probably +move from f800 to fe00, providing another 1.5KB, but TPL is only about 19KB so +there is no need to change it at present. The size limit is enforced by +CONFIG_TPL_SIZE_LIMIT to avoid producing images that won't boot. + +TPL (running from start.S) first sets up CAR (Cache-as-RAM) which provides +larger area of RAM for use while booting. CAR is mapped at CONFIG_SYS_CAR_ADDR +(fef00000) and is 768KB in size. It then sets up the stack in the botttom 64KB +of this space (i.e. below fef10000). This means that the stack and early +malloc() region in TPL can be 64KB at most. + +TPL operates without CONFIG_TPL_PCI enabled so PCI config access must use the +x86-specific functions pci_x86_write_config(), etc. SPL creates a simple-bus +device so that PCI devices are bound by driver model. Then arch_cpu_init_tpl() +is called to early init on various devices. This includes placing PCI devices +at hard-coded addresses in the memory map. PCI auto-config is not used. + +Most of the 16KB ROM is mapped into the very top of memory, except for the +Intel descriptor (first 4KB) and the space for SRAM as above. + +TPL does not set up a bloblist since at present it does not have anything to +pass to SPL. + +Once TPL is done it loads SPL from ROM using either the memory-mapped SPI or by +using the Intel fast SPI driver. SPL is loaded into CAR, at the address given +by CONFIG_SPL_TEXT_BASE, which is normally fef10000. + +Note that booting using the SPI driver results in an TPL image that is about +26KB in size instead of 19KB. Also boot speed is worse by about 340ms. If you +really want to use the driver, enable CONFIG_APL_SPI_FLASH_BOOT and set +BOOT_FROM_FAST_SPI_FLASH to true[2]. + + +Boot flow - SPL +--------------- + +SPL (running from start_from_tpl.S) continues to use the same stack as TPL. +It calls arch_cpu_init_spl() to set up a few devices, then init_dram() loads +the FSP-M binary into CAR and runs to, to set up SDRAM. The address of the +output 'HOB' list (Hand-off-block) is stored into gd->arch.hob_list for parsing. +There is a 2GB chunk of SDRAM starting at 0 and the rest is at 4GB. + +PCI auto-config is not used in SPL either, but CONFIG_SPL_PCI is defined, so +proper PCI access is available and normal dm_pci_read_config() calls can be +used. However PCI auto-config is not used so the same static memory mapping set +up by TPL is still active. + +SPL on x86 always runs with CONFIG_SPL_SEPARATE_BSS=y and BSS is at 120000 +(see u-boot-spl.lds). This works because SPL doesn't access BSS until after +board_init_r(), as per the rules, and DRAM is available then. + +SPL sets up a bloblist and passes the SPL hand-off information to U-Boot proper. +This includes a pointer to the HOB list as well as DRAM information. See +struct arch_spl_handoff. The bloblist address is set by CONFIG_BLOBLIST_ADDR, +normally 100000. + +SPL uses SPI flash to update the MRC caches in ROM. This speeds up subsequent +boots. Be warned that SPL can take 30 seconds without this cache! This is a +known issue with Intel SoCs with modern DRAM and apparently cannot be improved. +The MRC caches are used to work around this. + +Once SPL is finished it loads U-Boot into SDRAM at CONFIG_SYS_TEXT_BASE, which +is normally 1110000. Note that CAR is still active. + + +Boot flow - U-Boot pre-relocation +--------------------------------- + +U-Boot (running from start_from_spl.S) starts running in RAM and uses the same +stack as SPL. It does various init activities before relocation. Notably +arch_cpu_init_dm() sets up the pin muxing for the chip using a very large table +in the device tree. + +PCI auto-config is not used before relocation, but CONFIG_PCI of course is +defined, so proper PCI access is available. The same static memory mapping set +up by TPL is still active until relocation. + +As per usual, U-Boot allocates memory at the top of available RAM (a bit below +2GB in this case) and copies things there ready to relocate itself. Notably +reserve_arch() does not reserve space for the HOB list returned by FSP-M since +this is already located in RAM. + +U-Boot then shuts down CAR and jumps to its relocated version. + + +Boot flow - U-Boot post-relocation +--------------------------------- + +U-Boot starts up normally, running near the top of RAM. After driver model is +running, arch_fsp_init_r() is called which loads and runs the FSP-S binary. +This updates the HOB list to include graphics information, used by the fsp_video +driver. + +PCI autoconfig is done and a few devices are probed to complete init. Most +others are started only when they are used. + +Note that FSP-S is supposed to run after CAR has been shut down, which happens +immediately before U-Boot starts up in its relocated position. Therefore we +cannot run FSP-S before relocation. On the other hand we must run it before +PCI auto-config is done, since FSP-S may show or hide devices. The first device +that probes PCI after relocation is the serial port, in initr_serial(), so FSP-S +must run before that. A corollary is that loading FSP-S must be done without +using the SPI driver, to avoid probing PCI and causing an autoconfig, so +memory-mapped reading is always used for FSP-S. + +It would be possible to tear down CAR in SPL instead of U-Boot. The SPL handoff +information could make sure it does not include any pointers into CAR (in fact +it doesn't). But tearing down CAR in U-Boot allows the initial state used by TPL +and SPL to be read by U-Boot, which seems useful. It also matches how older +platforms start up (those that don't use SPL). + + +Performance +----------- + +Bootstage is used through all phases of U-Boot to keep accurate timimgs for +boot.
