2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2016-09-21MIPS: Malta: Enable CM & L2 supportPaul Burton
Enable support for the MIPS Coherence Manager & L2 caches on the MIPS Malta board, removing the need for us to attempt to bypass the L2 during boot (which would fail with recent CPUs that expose L2 config via the CM anyway). Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2016-05-31malta: Allow MIPS64 buildsPaul Burton
Both real Malta boards & emulators that mimic Malta (eg. QEMU) can support MIPS64 CPUs. Allow MIPS64 builds of U-Boot for such boards, which enables the user to make use of the whole 64 bit address space. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2016-05-21malta: Remove ".set mips32" directivePaul Burton
We always build for a mips32 or higher ISA, so this ".set mips32" directive is redundant. Once MIPSr6 support is added it will become harmful since some instruction encodings change & this directive will cause the older encodings to be incorrectly emitted instead of the appropriate ones for the build. In preparation for supporting MIPSr6, remove this redundant directive. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09malta: disable L2 cachesPaul Burton
Malta boards may be used with cores which support L2 caches, however U-boot does not yet support L2 cache for MIPS. Thus for the moment we'll disable L2 caches by setting the L2B bit in Config2. This is specific to MTI/Imagination MIPS cores which is why this is done for the Malta board rather than generically. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09malta: support for coreFPGA6 boardsPaul Burton
This patch adds support for running on Malta boards using coreFPGA6 core cards, including support for the msc01 system controller used with them. The system controller is detected at runtime allowing one U-boot binary to run on a Malta with either. Due to the PCI I/O base differing between Maltas using gt64120 & msc01 system controllers, the UART setup is modified slightly. A second UART is added so that there is one pointing at the correct address for each system controller. The Malta board then defines its own default_serial_console function to select the correct one at runtime. The incorrect UART will simply not function. Tested on: - A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both with and without an L2 cache. - QEMU. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09qemu-malta: rename to just "malta"Paul Burton
This is in preparation for adapting this board to function correctly on a physical MIPS Malta board. The board is moved into an "imgtec" vendor directory at the same time in order to ready us for any other boards supported by Imagination in the future.
