[PATCH 1/4] ARM: config: aspeed: Enable hardened allocator feature

[Joel Stanley]

SLAB_FREELIST_HARDENED can protect from freelist overwrite attacks with
really small overhead.

It works best with the SLUB allocator, so make SLUB the default by
removing SLAB=y.

      total   used           free           shared        buff/cache    available
SLAB  425596  44065.3+/-220  311099+/-3800  14864+/-3900  70432+/-3700  352767+/-3900

SLUB  425592  44225.3+/-280  313275+/-600   12132+/-3.3   68092+/-530   355295+/-280

These figures are the average memory usage from three boots of each
option in qemu, running the Romulus userspace. The output is from
free(1), reported in kilobytes.

[PATCH 2/4] ARM: config: aspeed: Enable KCS adapter for raw SerIO

[Joel Stanley]

Raw SerIO is used by the OpenBMC debug-trigger application to take
signals from the host that applications are unresponsive on the BMC.

[PATCH 3/4] ARM: config: aspeed_g4: Enable EDAC and SPGIO

[Joel Stanley]

These two devices are part of the AST2400 and the drivers have support
for that version of the soc.

[PATCH 4/4] ARM: config: aspeed: Regenerate defconfigs

[Joel Stanley]

A make defconfig && make savedefconfig was performed for each
configuration.

Most changes are due to options moving around, except for the following
which are due to changing defaults:

 - SECCOMP is enabled by default as of commit 282a181b1a0d ("seccomp:
   Move config option SECCOMP to arch/Kconfig") in v5.9

 - The soc drivers ASPEED_LPC_CTRL, ASPEED_LPC_SNOOP and ASPEED_P2A_CTRL
   are enabled by default when the aspeed platform is enabled, as of
   commit 592693a1f881 ("soc: aspeed: Improve kconfig") in v5.9

 - The ZBOOT_ROM_TEXT/BSS values fall out of the defconfig as of
   commit 39c3e304567a ("ARM: 8984/1: Kconfig: set default
   ZBOOT_ROM_TEXT/BSS value to 0x0") in v5.8

- I2C_MUX is selected by MEDIA_SUBDRV_AUTOSELECT, probably as of about
  v5.8. It was in the config as it is required bt the PCA I2C muxes that
  enabled it
