Default the drivers to on as most configurations will use them. Signed-off-by: Joel Stanley <joel@jms.id.au>

2020-09-25soc: aspeed-lpc-ctrl: LPC to AHB mapping on ast2600Joel Stanley
The ast2600 disables the mapping of AHB memory regions by default, only allowing the LPC window to point to SPI NOR. In order to point the window to any AHB address, an ast2600 specific bit must be toggled.

Alignment is a hardware constraint of the LPC2AHB bridge, and misaligned reserved memory will present as corrupted data.

2020-09-21soc: aspeed: Improve kconfigJoel Stanley
Reword the kconfig text to be consistent and reflect that most drivers are available for all supported ASPEED chips (2400, 2500 and 2600). Rearrange the symbols the SoC drivers depend on so the menu doesn't appear unless you are building for ASPEED for compile testing. The SYSCON_MFD and REGMAP options are usually selected by drivers that need them, so do this.

2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2019-12-05soc: aspeed: Fix snoop_file_poll()'s return typeLuc Van Oostenryck
snoop_file_poll() is defined as returning 'unsigned int' but the .poll method is declared as returning '__poll_t', a bitwise type. Fix this by using the proper return type and using the EPOLL constants instead of the POLL ones, as required for __poll_t.
