AER registers start at mvebu offset 0x0100. Registers PCI_ERR_ROOT_COMMAND, PCI_ERR_ROOT_STATUS and PCI_ERR_ROOT_ERR_SRC are not supported on pre-XP hardware and returns zeros. Note that AER interrupt is not supported yet as mvebu emulated bridge does not implement interrupts support at all yet. Also remove custom macro PCIE_HEADER_LOG_4_OFF as it is unused and correctly this register should be referenced via standard macros with offset, e.g. as: PCIE_CAP_PCIERR_OFF + PCI_ERR_HEADER_LOG + 4.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
