[PATCH] lib/date: Make rtc_mktime and mktime64 Y2038-ready
by Jan Kiszka 06 May '22

06 May '22

From: Jan Kiszka <jan.kiszka(a)siemens.com> We currently overflow due to wrong types used internally in rtc_mktime, on all platforms, and we return a too small type on 32-bit. One consumer that directly benefits from this is mktime64. Many others may still store the result in a wrong type. While at it, drop the redundant cast of mon in rtc_mktime (obsoleted by 714209832db1).

[PATCH] tools/imagetool: Fix segfault when tparams->verify_header is NULL
by Nicolas Heemeryck 06 May '22

On some image types like i.MX8 and i.MX8M, the verify_header function is not implemented. Before this commit, no check on tparams->verify_header was done causing a segfault if NULL.

[PATCH v2 0/9] spl: Use common function for loading/parsing images
by Sean Anderson 05 May '22

05 May '22

This series adds support for loading all image types (Legacy, FIT (with and without LOAD_FIT_FULL), and i.MX) to the MMC, SPI, NOR, NET, FAT, and EXT load methods. It does this by introducing a helper function which handles the minutiae of invoking the proper parsing function, and reading the rest of the image. Hopefully, this will make it easier for load methods to support all image types that U-Boot supports, without having undocumented unsupported image types. I applied this to several loaders which were invoking spl_load_simple_fit and/or spl_parse_image_header, but I did not use it with others (e.g. DFU/RAM) which had complications in the mix. Here's some bloat-o-meter for j7200_evm_a72_defconfig with ext4 support enabled: add/remove: 1/0 grow/shrink: 2/4 up/down: 224/-236 (-12) Function old new delta spl_load - 176 +176 spl_fit_read 60 104 +44 spl_load_image_ext 364 368 +4 spl_nor_load_image 120 108 -12 spl_spi_load_image 280 228 -52 spl_load_image_fat 320 264 -56 spl_mmc_load 716 600 -116 Total: Before=264556, After=264544, chg -0.00% ext4 support is +48 bytes, because the original image support was so bare-bones (just legacy/raw images). For most boards with a few load methods (where one of them isn't ext4), this series should be no bloat or a net negative. However, in the worst case this series will add 150-180 bytes. I haven't tested most of this, so please try booting your favorite board with NOR/SPI flash, FAT, or falcon mode. I had a nand conversion in here as well, but dropped due to difficulties outlined in [1].

[PATCH] include: configs: am**x/j721e/j721s2_evm.h: Move the stack pointer init address in arm64
by Aswath Govindraju 05 May '22

05 May '22

Currently, in case of arm64 bootloader and U-Boot the stack pointer is initialized at an offset of NON_SECURE_MSRAM_SIZE from arm64 SPL's text base address. After jumping to arm64, execution is done out of DDR. Therefore, having an offset corresponding to the size of MSRAM does not have any significance. Instead, initialize the stack pointer after an offset of 4MB from the SPL text base address. This helps in allocating larger memory for stack. ┌────────────────────┐0x80080000 │ │ │ arm64 SPL │ ├────────────────────┤ │ ▲ │ │ │ │ │ STACK │ ├────────────────────┤0x80480000 │ Memory for Load │ │ Buffer Allocation │ ├────────────────────┤0x80800000 │ │ │ U-Boot Image │ │ │ └────────────────────┘ Signed-off-by: Aswath Govindraju <a-govindraju(a)ti.com> --- Notes: - Verified SD and DFU boot modes on platforms where this change will have an effect and are supported - AM64 - SD boot mode, https://pastebin.ubuntu.com/p/YDBjhTqwSK/ - DFU boot mode, https://pastebin.ubuntu.com/p/Xsjn4h7h2W/ - "Error setting up memory banksize. -22" This error was present even without the changes done by this patch - J721e - SD boot mode, https://pastebin.ubuntu.com/p/NpVvKjMMxc/ - DFU boot mode, https://pastebin.ubuntu.com/p/MZPS4Wmkj5/ - J7200 - SD boot mode, https://pastebin.ubuntu.com/p/QyyC8WFsS2/ - DFU boot mode, https://pastebin.ubuntu.com/p/Nmjf3mVRyH/ - J721s2 - SD boot mode, https://pastebin.ubuntu.com/p/xh96CP8ndB/ - AM654 - SD boot mode, https://pastebin.ubuntu.com/p/DbFjFSvj2C/ include/configs/am64x_evm.h | 3 +-- include/configs/am65x_evm.h | 3 +-- include/configs/j721e_evm.h | 3 +-- include/configs/j721s2_evm.h | 3 +-- 4 files changed, 4 insertions(+), 8 deletions(-) diff --git a/include/configs/am64x_evm.h b/include/configs/am64x_evm.h index 135cb3c2ee20..d84a8db97ede 100644 --- a/include/configs/am64x_evm.h +++ b/include/configs/am64x_evm.h @@ -24,8 +24,7 @@ #define CONFIG_SPL_MAX_SIZE CONFIG_SYS_K3_MAX_DOWNLODABLE_IMAGE_SIZE #if defined(CONFIG_TARGET_AM642_A53_EVM) -#define CONFIG_SYS_INIT_SP_ADDR (CONFIG_SPL_TEXT_BASE + \ - CONFIG_SYS_K3_NON_SECURE_MSRAM_SIZE - 4) +#define CONFIG_SYS_INIT_SP_ADDR (CONFIG_SPL_TEXT_BASE + SZ_4M) #else /* * Maximum size in memory allocated to the SPL BSS.

[PATCH v4 0/3] Add support for different mediatek pinctrl designs
by Sam Shih 05 May '22

05 May '22

MediaTek SoC's pinconf register usage varies by SoC, So the original code uses V0/V1 to mark different pinconf design. But actually, the real difference is the design of the "pin" itself. Different SoCs will choose specify "pin design", which we call the "io_type" of the pin. For a better understanding of mediatek pinctrl design. and make the driver clear and flexible, this patch series changes common parts of mediatek pinctrl driver to support various pinctrl controller designs. The following mediatek config were tested to ensure the build passed: - mt7622_rfb_defconfig - mt7623a_unielec_u7623_02_defconfig - mt7623n_bpir2_defconfig - mt7629_rfb_defconfig - mt8183_pumpkin_defconfig - mt8512_bm1_emmc_defconfig - mt8516_pumpkin_defconfig - mt8518_ap1_emmc_defconfig --- v4: fix mt8518_ap1_emmc build fail v3: fix v2 patch series misapplied v2: fix build fail caused by patch [2/3] Sam Shih (3): pinctrl: mediatek: rewrite mtk_pinconf_set and related functions pinctrl: mediatek: introduce multiple memory bases support pinctrl: mediatek: add support for different types of IO pins drivers/pinctrl/mediatek/pinctrl-mtk-common.c | 221 ++++++++++++++---- drivers/pinctrl/mediatek/pinctrl-mtk-common.h | 78 ++++++- 2 files changed, 248 insertions(+), 51 deletions(-) -- 2.18.0
