Hi all,

This is a huge series which promoted MIPS/Boston target into a usable state, with fixes to drivers and general framework issues I found in this process.

I also converted the target to OF_UPSTREAM.

This target is covered by QEMU, to test on QEMU: ``` make boston64r6el_defconfig make qemu-system-mips64el -M boston -cpu I6500 -bios ./u-boot.bin -nographic ```

This is my first u-boot contribution, please kindly advise if you have any comments.

Thanks

New subject: [PATCH v2 01/12] pci: xilinx: Handle size of ecam region properly

Probe size of ecam from devicetree properly and cap accessible bus number accorading to ecam region size to ensure we don't go beyond hardware address space.

Also disable all interrupts to ensure errors are handled silently.

Boston has a very limited memory range for PCI controllers, where 1MB can't easily fit into it.

New subject: [PATCH v2 03/12] pci: Enable PCI_MAP_SYSTEM_MEMORY when ARCH_MAP_SYSMEM is not set

For MIPS we are always looking gd->dram in virtual address so PCI_MAP_SYSTEM_MEMORY should always be enabled.

If in future we ever want to make it physical we have to set ARCH_MAP_SYSMEM.

New subject: [PATCH v2 04/12] ahci: DMA addressing fixes

Ensure that we are using correct physical/virtual address for DMA buffer write and hardware register settings.

The convention is: in ahci_ioports all pointers are virtual, that will be converted to physical address when writing to hardware registers or into sg/cmd_tbl.

Also fixed 64bit physical address support for dwc_ahsata, ensure higher bits are written into registers/sg properly.

Use memalign for allocating aligned buffer in dwc_ahsata so we don't have to do our own alignment in driver.

Remove hard dependencies to arch headers, get clock from clk subsystem if arch clock function is not available, align compatible strings with devicetree binding.

No functional change on existing platforms, just get it build on other platforms.

New subject: [PATCH v2 12/12] mailmap: Update email for Paul Burton

Paul had left MIPS a couple of years ago, his email address is no longer valid.

Replace it with his kenrel.org email, which has been used in kernel and QEMU, in case we still want to reach him.
