global_data: Add a generic global_data flag for SMP state

2020-07-20T01:46:45+00:00

Allow keeping track of whether all CPUs have been enabled yet. This allows
us to know whether other CPUs need to be considered when updating
CPU-specific settings such as MTRRs on x86.

board: Add a gd flag for chain loading

2020-04-30T09:40:16+00:00

When U-Boot is run from another boot loader, much of the low-level init
needs to be skipped.

Add a flag for this and adjust ll_boot_init() to use it.

global_data.h: make self-contained

2020-03-16T16:49:09+00:00

The compiler never knows what 'bd_t' is without including .

By changing it to (struct bd_info), the compiler learns it is struct.

global_data: remove unused mxc_i2c specific field

global_data: Remove comment of reserved arch-specific GD flags

2019-08-18T13:54:10+00:00

With the removal of the x86 specific GD flags, there are no arch-
specific GD flags any more. Let's remove the comment about reserving the
upper 16 bits for arch-specific flags in the common header. This gives
us more flexibility with the usage of the GD flags.

As a matter of fact, we are already using more than 16 bits for common
GD flags (with the addition of GD_FLG_WDT_READY).

watchdog: Split WDT from SPL_WDT

2019-07-19T18:14:50+00:00

Use CONFIG_IS_ENABLED(WDT) to permit use of WDT in SPL without DM,
while the full U-Boot can use rich DM/DT WDT driver.

watchdog: Implement generic watchdog_reset() version

2019-04-26T07:16:32+00:00

This patch tries to implement a generic watchdog_reset() function that
can be used by all boards that want to service the watchdog device in
U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG.

Without this approach, new boards or platforms needed to implement a
board specific version of this functionality, mostly copy'ing the same
code over and over again into their board or platforms code base.

With this new generic function, the scattered other functions are now
removed to be replaced by the generic one. The new version also enables
the configuration of the watchdog timeout via the DT "timeout-sec"
property (if enabled via CONFIG_OF_CONTROL).

This patch also adds a new flag to the GD flags, to flag that the
watchdog is ready to use and adds the pointer to the watchdog device
to the GD. This enables us to remove the global "watchdog_dev"
variable, which was prone to cause problems because of its potentially
very early use in watchdog_reset(), even before the BSS is cleared.

dm: core: Change platform specific translation-offset handling

2019-04-24T02:26:43+00:00

Testing has shown that the current DM implementation of a platform /
board specific translation offset, as its needed for the SPL on MVEBU
platforms is buggy. The translation offset is confingured too late,
after the driver bind functions are run. This may result in incorrect
address translations. With the current implementation its not possible
to configure the offset earlier, as the DM code has not run at all.

This patch now removed the set_/get_translation_offset() calls and
moves the translation offset into the GD variable translation_offset.
This variable will get used when CONFIG_TRANSLATION_OFFSET is enabled.
This option is enabled only for MVEBU on ARM32 platforms, where its
currenty needed and configured in the SPL.

lib: fdtdec: Add function re-setup the fdt more effeciently

2018-12-10T06:21:21+00:00

In some cases it may be useful to be able to change the fdt we have been
using and use another one instead. For example, the TI platforms uses an
EEPROM to store board information and, based on the type of board,
different dtbs are used by the SPL. When DM_I2C is used, a first dtb must
be used before the I2C is initialized and only then the final dtb can be
selected.
To speed up the process and reduce memory usage, introduce a new function
fdtdec_setup_best_match() that re-use the DTBs loaded in memory by
fdtdec_setup() to select the best match.
