2019-12-15x86: Separate out U-Boot and device tree in ROM imageSimon Glass
At present binman does not support updating a device tree that is part of U-Boot (i.e u-boot.bin). Separate the entries into two so that we can get updated entry information. This makes binman_entry_find() work correctly. Do the same for SPL tool. In both cases, group the two parts into a section so that SPL symbols get the correct total size. It may be possible for binman to handle this automatically at some point, by ignoring u-boot.bin and always creating it from u-boot-nodtb.bin and u-boot.dtb Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-12-15x86: Don't repeat microcode in U-Boot if not neededSimon Glass
At present if SPL sets up the microcode then it is still included in U-Boot as well. This is wasteful as microcode is large. Adjust the logic in the image to prevent this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2019-12-15x86: Add an option to control the position of SPLSimon Glass
For Apollo Lake SPL is run from CAR (cache-as-RAM) which is in a different location from where SPL must be placed in ROM. In other words, although SPL runs before SDRAM is set up, it is not execute-in-place (XIP). Add a Kconfig option for the ROM position.

2019-12-15x86: Add an option to control the position of U-BootSimon Glass
The existing work-around for positioning U-Boot in the ROM when it actually runs from RAM still exists and there is not obvious way to change this. Add a proper Kconfig option to handle this case.

2019-12-15x86: Add an option to include a FITSimon Glass

At present these two sections of code are linked together into a single 2KB chunk in a single file. Some Intel SoCs like to have a FIT (Firmware Interface Table) in the ROM and the pointer for this needs to go at 0xffffffc0 which is in the middle of these two sections.

2018-08-20x86: coreboot: Add generic coreboot payload supportBin Meng
Currently building U-Boot as the coreboot payload requires user to change the build configuration for a specific board during menuconfig process. This uses the board's native device tree to configure the hardware. For example, the device tree provides PCI address range for the PCI host controller and U-Boot will re-program all PCI devices' BAR to be within this range. In order to make sure we don't mess up the hardware, we should guarantee the range matches what coreboot programs the chipset. But we really should make the coreboot payload support easier. Just like EFI payload, we can create a generic coreboot payload for all x86 boards as well. The payload is configured to include as many generic drivers as possible. All stuff that touches low level initialization are not allowed as such is the coreboot's responsibility. Platform specific drivers (like gpio, spi, etc) are not included.

2018-08-01binman: Rename 'position' to 'offset'Simon Glass
After some thought, I believe there is an unfortunate naming flaw in binman. Entries have a position and size, but now that we support hierarchical sections it is unclear whether a position should be an absolute position within the image, or a relative position within its parent section. At present 'position' actually means the relative position. This indicates a need for an 'image position' for code that wants to find the location of an entry without having to do calculations back through parents to discover this image position. A better name for the current 'position' or 'pos' is 'offset'. It is not always an absolute position, but it is always an offset from its parent offset. It is unfortunate to rename this concept now, 18 months after binman was introduced. However I believe it is the right thing to do. The impact is mostly limited to binman itself and a few changes to in-tree users to binman: tegra sunxi x86 The change makes old binman definitions (e.g. downstream or out-of-tree) incompatible if they use the 'pos = <...>' property. Later work will adjust binman to generate an error when it is used. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

Sometimes kernel just oops, while sometimes kernel throws MCE errors and hangs: mce: [Hardware Error]: Machine check events logged mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 4: c400000000010151 mce: [Hardware Error]: TSC 0 ADDR 130f3f2c0 mce: [Hardware Error]: PROCESSOR 0:406c3 TIME 1508160686 SOCKET 0 APIC 0 microcode 363 This looks like a hardware error per mcelog. After debugging, it seems turning off turbo mode on the processor does not expose this behavior, although U-Boot runs OK with turbo mode on. Suspect it is related to an errata of Braswell processor. To fix this, remove the Braswell cpu driver which does the turbo mode configuration, and switch to use the generic cpu-x86 driver.
