[PATCH 00/23] Add i.MX8ULP A1 revision support
by Ye Li 29 Mar '23

29 Mar '23

The patch set is used to support i.MX8ULP A1 revision. It includes below changes: a) XRDC/TRDC are enabled by default on A1 via DBD_EN fuse programmed. So necessary changes for XRDC setting are added. And TRDC is totally moved to RTD. A handshake is added to sync with RTD for the XRDC and TRDC setting completion. b) S400 API update and fuse update c) DDR timing and driver update d) clock setting update to match max rate restriction e) uPower API update and code clean Jacky Bai (2): ddr: imx: Update the ddr init flow on imx8ulp imx8ulp_evk: Update the DDR timing Peng Fan (3): imx: imx8ulp: upower: replace magic number with macro imx: imx8ulp: upower: make code cleaner imx8ulp_evk: disable overflow of port0 for LPAV Ye Li (18): imx: imx8ulp: Fix MU device probe failure imx: imx8ulp: Get chip revision from Sentinel imx: imx8ulp: Limit the eMMC ROM API workaround to A0.1 part imx: imx8ulp: Set XRDC MRC4/5 for access DDR from APD imx: imx8ulp: Remove the TRDC configure from A35 imx: imx8ulp: Adjust handshake to sync TRDC and XRDC completion imx: imx8ulp: configure XRDC for DRAM access from S400 ddr: imx8ulp: Change DRAM timing save area to 0x20055000 imx: imx8ulp: Reconfigure MRC3 for SRAM0 access imx: imx8ulp: Clear dividers in PLL3DIV_PFD registers imx: imx8ulp: Configure XRDC PDAC and MSC for DBD owner=S400 only imx: imx8ulp: Update clocks to meet max rate restrictions imx: sentinel: Update S400 API get info message structure misc: fuse: Update fuse mapping for 8ULP S400 API misc: fuse: Lock 8ULP ECC-protected fuse when programming imx8ulp_evk: Change to use DDR driver imx8ulp_evk: Update DDR ports arbitration for DCNANO underrun imx8ulp_evk: Clear data at fdt_addr_r before booting kernel arch/arm/include/asm/arch-imx8ulp/imx-regs.h | 1 + arch/arm/include/asm/arch-imx8ulp/rdc.h | 1 + arch/arm/include/asm/arch-imx8ulp/sys_proto.h | 2 + arch/arm/include/asm/global_data.h | 3 + arch/arm/include/asm/mach-imx/s400_api.h | 2 + arch/arm/mach-imx/imx8ulp/Kconfig | 1 + arch/arm/mach-imx/imx8ulp/cgc.c | 70 ++++---- arch/arm/mach-imx/imx8ulp/clock.c | 50 +++--- arch/arm/mach-imx/imx8ulp/rdc.c | 71 ++++++++ arch/arm/mach-imx/imx8ulp/soc.c | 208 ++++++++++++++++++----- arch/arm/mach-imx/imx8ulp/upower/upower_hal.c | 112 +++++++++++-- board/freescale/imx8ulp_evk/Makefile | 2 +- board/freescale/imx8ulp_evk/ddr_init.c | 207 ----------------------- board/freescale/imx8ulp_evk/imx8ulp_evk.c | 16 +- board/freescale/imx8ulp_evk/lpddr4_timing.c | 210 ++++++++++++------------ board/freescale/imx8ulp_evk/lpddr4_timing_266.c | 6 +- board/freescale/imx8ulp_evk/spl.c | 18 +- drivers/ddr/imx/imx8ulp/Kconfig | 2 +- drivers/ddr/imx/imx8ulp/ddr_init.c | 55 +++++-- drivers/misc/sentinel/fuse.c | 32 +++- 20 files changed, 605 insertions(+), 464 deletions(-) delete mode 100644 board/freescale/imx8ulp_evk/ddr_init.c -- 2.7.4

[QUESTION] Clear a local variable in hush shell
by Stefan Herbrechtsmeier 29 Mar '23

29 Mar '23

Hi, what is the correct way to clear a local variable in the hush shell? The "c=" doesn't work because the commit "common: cli_hush: avoid dead code" (aa722529635c16c52d9d609122fecc96ec8d03e4) explicitly change the function set_local_var to return -1 if a value is missing.

[PATCH v2 1/2] regulator: implement basic reference counter
by Eugen Hristev 29 Mar '23

29 Mar '23

Some devices share a regulator supply, when the first one will request regulator disable, the second device will have it's supply cut off before graciously shutting down. Hence there will be timeouts and other failed operations. Implement a reference counter mechanism similar with what is done in Linux, to keep track of enable and disable requests, and only disable the regulator when the last of the consumers has requested shutdown.

[PATCH v3 0/5] Add Broadcom Northstar basic support
by Linus Walleij 29 Mar '23

29 Mar '23

This adds the device trees and minimal code needed to run U-Boot on Broadcom Northstar SoCs. This is needed to properly boot the D-Link DIR-890L router as it refuse to directly boot compressed kernels bigger than 2MB, and well our compressed kernel is bigger than 2MB so let's put in U-Boot. While it is a bit tailored to this usecase (it can probably also be used with the DIR-885L without modifications) it forms a base that can be used to support more Northstar boards. I have this working with DIR-890L and OpenWrt: https://dflund.se/~triad/krad/dlink-dir-890l/ ChangeLog v1->v3: - Bundle with the iproc NAND and nand base pacthes as the iproc patch is a prerequisite. - Jump from v1->v3 as the other patches was at version v3. It is a bit of a mystery to me who can merge this patches... BRCM custodian?
