[U-Boot] [PATCH v2 0/7] AM65x HS device support
by Andrew F. Davis 12 Apr '19

12 Apr '19

Hello all, This series brings up HS device support on the AM65x platform. Support for HS on K3 family devices is a bit different than previous devices but for the most part all that has been abstracted into the SECDEV package, allowing for a rather straight forward implementation here. Thanks, Andrew Changes from v1: - Commented on use of .data section - Use ti_sci_msg_hdr header directly when possible - Rebase and add Reviewed-bys - Will add makefile cleanup later as it also affects files unrelated to this series Andrew F.

[U-Boot] [PATCH] ARM: am3517_evm: Add spl_start_uboot for Falcon Mode
by Adam Ford 12 Apr '19

12 Apr '19

When booting the am3517-evm, the following message appears: SPL: Please implement spl_start_uboot() for your board SPL: Direct Linux boot not active! This patch implements spl_start_uboot to clear this message and allow device to know if it should boot U-Boot or kernel.

[U-Boot] [PATCHv2 1/2] ti: keystone2: Move CONFIG_ISW_ENTRY_ADDR to a common place
by Tom Rini 12 Apr '19

12 Apr '19

The ISW_ENTRY_ADDR Kconfig option under mach-omap2 isn't a SoC specific notion but rather "where is our previous stage loaded in memory?" option. Make use of this on ARCH_KEYSTONE rather than SPL_TEXT_BASE for our HS builds that are not using SPL anyhow. Cc: Vitaly Andrianov <vitalya(a)ti.com> Cc: Andrew F.

[U-Boot] [PATCH 00/11] Fix Ethernet boot in am335x
by Faiz Abbas 12 Apr '19

12 Apr '19

The following patches fix ethernet boot in am335x. Enabling OF_CONTROL in SPL makes it overflow the sram size. To avoid this, I am using static platdata in the am335x board file instead of the fdtdec_*() calls used in ofdata_to_platdata(). Patches 1-5 isolate the two operations of getting platform data (all of which should happen in _ofdata_to_platdata()) and initial configurations (all of which should happen in _probe()). Patch 6 makes sure the cpsw driver gets probed in SPL. Patch 7 adds static platdata to the am335 board file. Patches 8-10 makes changes in the config to make space for and enable ETH_SUPPORT in SPL. Patch 11 removes non-DM_ETH code from the am335x board file. Tested ethernet boot and tftp in am335x-evm. Regression tested on dra71x-evm.

[U-Boot] [PATCH] armv7R: K3: am654: Trigger panic on DDR init failures
by Andreas Dannenberg 12 Apr '19

12 Apr '19

When initializing DDR from R5 SPL trigger U-Boot's panic facility rather than simply returning from the board init function as there is little point continuing code execution. Further, as panic implies a board reset, so using it might potentially allow to recover from this error in certain cases such as when the init failure was caused by a temporary glitch of some sorts.

[U-Boot] [PATCH V3 1/2] davinci: da850evm/omapl138-lcdk: Move BSS to SDRAM because SRAM is full
by Adam Ford 12 Apr '19

12 Apr '19

In order to fully support SPL_OF_CONTROL, we need BSS to be a bit larger. This patch relocates BSS to SDRAM instead of SRAM which is similar to how ARMv7 boards (like OMAP2+) do it. This means two new variables are required: CONFIG_SPL_BSS_START_ADDR set to DAVINCI_DDR_EMIF_DATA_BASE CONFIG_SPL_BSS_MAX_SIZE is set to 0x1080000 which is 1 byte before the location where U-Boot will load.
