meta-aspeed: linux: enable ubi support based on file system type

2023-02-10T03:26:13+00:00

Both the `obmc-static-norootfs` and `obmc-ubi-fs` DISTRO_FEATURES enable an image that utilizes ubifs. Key off this in meta-aspeed to apply the correct kernel config snippet. Signed-off-by: Patrick Williams Change-Id: I15b0e24e9d0e454651a50b2d997b6aee01432ab9

meta-aspeed: Remove UBI from kernel config

2023-01-23T21:24:32+00:00

Most machines don't use UBI, so remove it from the kernel. Those that wish to use it can opt in with a machine specific kernel config snippet, as Witherspoon does. Signed-off-by: Joel Stanley Change-Id: I52803c299b15c8d85aefd00ae9f13785e4e9a06b

meta-aspeed: Remove CONFIG_IPMI_KCS_BMC_CDEV_RAW

2023-01-18T22:52:09+00:00

This is only used by certain IBM P10 and Tacoma systems. Let them explicitly enable the driver. Signed-off-by: Joel Stanley Change-Id: I384e5ab7587732f93617e05d06b700bc7421a81d

meta-aspeed: add HW_RANDOM to tpm kconfig

2022-11-18T20:03:11+00:00

Bletchley currently has the following compile warning: ``` WARNING: linux-aspeed-6.0.8+gitAUTOINC+1b16243b00-r0 do_kernel_configcheck: [kernel config]: specified values did not make it into the kernel's final configuration: [NOTE]: 'CONFIG_HW_RANDOM_TPM' last val (y) and .config val (n) do not match [INFO]: CONFIG_HW_RANDOM_TPM : n Config 'HW_RANDOM_TPM' has the following Direct dependencies (HW_RANDOM_TPM=n): TCG_TPM(=y) && HW_RANDOM(=m) && !(TCG_TPM(=y) = y && HW_RANDOM(=m) = m) (=n) ``` This is due to HW_RANDOM=m by default. Explicitly set HW_RANDOM=y in the tpm2 config snippet where HW_RANDOM_TPM=y is set. Change-Id: I7185cdab58de19dcf456d9aaad1c563fccc04d71

linux-aspeed: Remove FIRMWARE_MEMMAP

2022-10-06T04:01:30+00:00

It's an x86 thing, so it's dead code. Saves 1.6KB. Signed-off-by: Joel Stanley Change-Id: I96fce5c5355737bd1974089d0ad1538334340a62

linux-aspeed: Disable SLUB_DEBUG

2022-10-05T06:22:52+00:00

SLUB_DEBUG increases code size and has no known users in production BMC images. It was likely implicitly enabled when we switched from SLAB to SLUB in commit 271bf3dce908 ("meta-aspeed: Enable hardened allocator feature"). aspeed_g5_defconfig (v5.15): Total: Before=11329249, After=11309638, chg -0.17% aspeed_g5_defconfig (v6.0): Total: Before=11003344, After=10949112, chg -0.49% Built with arm-linux-gnueabihf-gcc (Debian 12.2.0-3). A saving of 19KB for the current kernel, and 54KB for the future kernel version. Change-Id: I446d6e8b6e9f4b717de9c3ee06e0b822e5cde75f Signed-off-by: Joel Stanley

linux-aspeed: Enable EDAC driver

2022-09-24T02:39:19+00:00

The Error Detection and Correction driver is used for reporting ECC errors to userspace. On a system that does not have ECC enabled it will not probe. Signed-off-by: Joel Stanley Change-Id: Id804e055eef6a6cc1696fedaf670d4ec125d1417 Signed-off-by: Joel Stanley

aspeed-g6: defconfig: Add support for USB flash drives

2022-05-25T13:41:36+00:00

Add support to detect USB flash drives and create the /dev/sd* devices. Also add support for vfat to support USB drives formatted as FAT32. This support will be used to enable firmware updates via USB flash drives where the firmware image is stored in the USB drive and it's plugged into the BMC USB port for AST2600 systems.

aspeed: Add TPM TIS I2C driver to tpm2 machine feature

2022-01-17T02:13:42+00:00

This driver requires CONFIG_TCG_TPM and CONFIG_TCG_TIS_I2C. Signed-off-by: Joel Stanley Change-Id: If461c2fec0874c09410388bcce7990334b81a726
