Subject: [U-Boot] [PATCH v2 0/2] x86: minimal ACPI support for Intel Tangier
Date: Tue, 3 Oct 2017 14:55:06 +0300 [thread overview]
Message-ID: <20171003115508.15215-1-andriy.shevchenko@linux.intel.com> (raw)
This brings initial support for Intel Merrifield platform (based on
Intel Tangier SoC) along with minimum support of Intel Edison board
(based on Merrifield).
This RFC series based on discussion [1] to show how we may unleash
the powerfulness of ACPI on the board, which initially didn't support
it, via U-Boot.
Note, pin control device is using compatible strings since there is
near to impossible to allocate ACPI ID for it. Patches to the kernel
to make it OF-enumerated driver are under review.
Note, I dunno the split of DSL pieces is fully correct since we need to
understand the difference between SoC, platform, and board terms. Even
though some stuff here declared under 'tangier' folder it's related to
Intel Merrifield platform (like Wi-Fi chip connected to SDIO port of
Intel Tangier). Because of some restrictions of ACPI language / interpreter
I may not split some of those parts. Thus, it needs to be revisited.
More information is available on [2].
