common: Implement A/B metadata

2019-07-24T17:16:29+00:00

This patch determines the A/B-specific bootloader message structure
that is the basis for implementation of recovery and A/B update
functions. A/B metadata is stored in this structure and used to decide
which slot should we use to boot the device. Also some basic functions
for A/B metadata manipulation are implemented (like slot selection).

The patch was extracted from commits [1], [2] with some coding style
fixes.

stm32mp1: ram: add interactive mode for DDR configuration

2019-05-23T09:38:11+00:00

This debug mode is used by CubeMX DDR tuning tools
or manualy for tests during board bring-up.
It is simple console used to change DDR parameters and check
initialization.

usb: Rename SPL_USB_SUPPORT to SPL_USB_STORAGE

2019-02-15T21:01:15+00:00

Since there is the SPL_USB_HOST_SUPPORT for enabling USB support in SPL,
makes more sense to rename the SPL_USB_SUPPORT as SPL_USB_STORAGE.
Everything that is not part of the usb storage support in SPL is now
build under SPL_USB_HOST_SUPPORT.

dfu: Remove dependency on HUSH parser in SPL

2019-01-26T13:13:55+00:00

CLI support with the HUSH parser is not currently SPL safe due to it's
use of realloc. That function is not defined for SPLs that use
SYS_MALLOC_SIMPLE. CLI support can be built in to SPL and some functions
do work, but use of some like run_command() will cause build to fail.
When no SPL code calls this function build works as the compiler removes
this unreachable code so the unresolved symbols are ignored.

If DFU support is enabled in SPL then MMU DFU support may get brought in
also, this code does make a call to run_command() causing build to fail
if the HUSH parser is not built-in. To break this odd and unneeded
dependency chain we use CONFIG_IS_ENABLED where appropriate to prevent
calls into HUSH code from SPL. This also removes our need to pull in the
rather unrelated source file when SPL_DFU is defined.

spl: Kconfig: Drop the _SUPPORT postfix from SPL_DFU

2019-01-26T13:13:54+00:00

The symbol CONFIG_SPL_DFU_SUPPORT in SPL build has the same
meaning as CONFIG_DFU in regular U-Boot. Drop the _SUPPORT
to allow for cleaner use in code.

usb: musb-new: Add support for DM_USB

2018-12-14T16:59:10+00:00

Enable DM for USB peripheral in the musb-new driver.
Also make sure that the driver can be used in the SPL.
This implies that:
* the driver must work with and without the OF_CONTROL option. That
in turn, implies that the platform data can be passed in a struct
ti_musb_platdata or be read from the dtb
* usb.o is linked in the SPL if host support is enabled

Another change is that the driver does not fail to bind (and stop the boot
process) if one of the child driver does not bind. Reporting the error is
enough. This kind of error would appear if the port is configured in the
DTS but the driver is not activated in the config.

usb: Remove CMD_USB dependency for common code

2018-11-26T20:19:03+00:00

Common USB code is built whenever USB is enabled (in non-SPL builds).
The USB uclass is built whenever (SPL_)DM_USB is enabled. Both need to
be independent from CMD_USB.

Add core support for a bloblist to convey data from SPL

2018-11-26T13:25:32+00:00

At present there is no standard way in U-Boot to pass information from SPL
to U-Boot proper. But sometimes SPL wants to convey information to U-Boot
that U-Boot cannot easily figure out. For example, if SPL sets up SDRAM
then it might want to pass the size of SDRAM, or the location of each
bank, to U-Boot proper.

Add a new 'bloblist' feature which provides this. A bloblist is set up in
the first phase of U-Boot that runs (i.e. TPL or SPL). The location of
this info may be in SRAM or CAR (x86 cache-as-RAM) or somewhere else.

Information placed in this region is preserved (with a checksum) through
TPL and SPL and ends up in U-Boot. At this point it is copied into SDRAM
so it can be used after relocation.
