Subject: [PATCH 06/11] pci, acpi, mcfg: Provide generic implementation of MCFG code initialization.
Date: Tue, 26 May 2015 20:49:19 +0800 [thread overview]
Message-ID: <1432644564-24746-7-git-send-email-hanjun.guo@linaro.org> (raw)
In-Reply-To: <1432644564-24746-1-git-send-email-hanjun.guo@linaro.org>
From: Tomasz Nowicki <tomasz.nowicki@linaro.org>
First function acpi_mcfg_check_entry() does not apply any quirks by default.
Last two functions are required by ACPI subsystem to make PCI config
space accessible. Generic code assume to do nothing for early init call but
late init call does as follow:
- parse MCFG table and add regions to ECAM resource list
- map regions
- add regions to iomem_resource
