watchdog: Implement generic watchdog_reset() version

2019-04-26T07:16:32Z

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

2019-04-24T02:26:43Z

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

2018-12-10T06:21:21Z

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.

spl: Add support for passing handoff info to U-Boot proper

2018-11-26T13:25:37Z

There is some basic informaton that SPL normally wants to pass through to U-Boot, such as the SDRAM size and bank information. Mkae use of the new bloblist structure for this. Add a new 'handoff' blob which is set up in SPL and passed to U-Boot proper. Also adda test for sandbox_spl that checks that this works correctly and a new 'sb' command to show the information passed from SPL. Reviewed-by: Tom Rini Signed-off-by: Simon Glass

Add include/asm-generic/atomic.h

2018-09-26T01:49:18Z

The arm, xtensa and mips version of atomic.h were already very similar (the mips one was a copy of xtensa). Combine these implementations together to produce a generic atomic.h that can be included by these architectures (and any others that need it in future).

arch: types.h: factor out fixed width typedefs to int-ll64.h

All architectures have the same definition for s8/16/32/64 and u8/16/32/64. Factor out the duplicated code into . BTW, Linux unified the kernel space definition into int-ll64.h a few years ago as you see in Linux commit 0c79a8e29b5f ("asm/types.h: Remove include/asm-generic/int-l64.h").

u-boot: remove driver lookup loop from env_save()

2018-07-30T11:18:47Z

When called with ENVOP_SAVE, env_get_location() only returns the gd->env_load_location variable without actually checking for the environment location and priority. This behaviour causes env_save() to fall into an infinite loop when the low-level drv->save() call fails. The env_save() function should not loop through the environment location list but it should save the environment into the location stored in gd->env_load_location by the last env_load() call.

fdt: Add device tree memory bindings

2018-07-09T15:11:00Z

Support a default memory bank, specified in reg, as well as board-specific memory banks in subtree board-id nodes. This allows memory information to be provided in the device tree, rather than hard-coded in, which will make it simpler to handle similar devices with different memory banks, as the board-id values or masks can be used to match devices.
