allwinner: Disable unused features to save space

2019-06-08T21:48:39Z

As all Allwinner platforms are single-cluster A53 chips, we can disable support for newer, unsupported architecture extensions. We can also avoid some cache maintenance code, since no platform-specific setup is required to enable coherency. These changes reduce the size of .text on a default build with GCC 9.1 enough that .vectors again fits in the second half of a page, instead of requiring its own page. This commit was boot-tested on the Pinebook. Signed-off-by: Samuel Holland Change-Id: Ib90454ef0c798d5e714b7780c585be0b1ed49c6d

plat: allwinner: common: use r_wdog instead of wdog

2019-04-10T23:57:24Z

Some Allwinner H6 has a broken watchdog that doesn't make the soc reboot. Use the R_WATCHDOG instead. Signed-off-by: Clément Péron Change-Id: Ie95cc30a80ed517b60b30d6bc2e655a1b53f18ba

allwinner: Clean up CPU ops functions

2019-02-18T03:12:51Z

Convert them to take an mpidr instead of a (cluster, core) pair. This simplifies all of the call sites, and actually makes the functions a bit smaller. Signed-off-by: Samuel Holland

allwinner: Constify data structures

2019-02-18T02:13:40Z

This maximizes the amount of data protected by the MMU. Signed-off-by: Samuel Holland

Sanitise includes across codebase

2019-01-04T10:43:17Z

Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

drivers/console: Link console framework code by default

2018-12-07T00:13:50Z

This patch makes the build system link the console framework code by default, like it already does with other common libraries (e.g. cache helpers). This should not make a difference in practice since TF is linked with --gc-sections, so the linker will garbage collect all functions and data that are not referenced by any other code. Thus, if a platform doesn't want to include console code for size reasons and doesn't make any references to console functions, the code will not be included in the final binary. To avoid compatibility issues with older platform ports, only make this change for the MULTI_CONSOLE_API. Change-Id: I153a9dbe680d57aadb860d1c829759ba701130d3 Signed-off-by: Julius Werner

allwinner: A64/H5: setup missing bus clocks

2018-11-14T09:36:44Z

The legacy Allwinner ATF port used to setup some clocks, and U-Boot is still relying on this. We don't need to setup the full set, as the SPL is doing most of it, but it misses one clock (AHB2) and programs another (AHB1) to quite conservative values. Fix this up during the platform setup to improve USB and Ethernet performance, iperf values go up by 31% in my setup with that patch. Signed-off-by: Andre Przywara

Standardise header guards across codebase

2018-11-08T10:20:19Z

All identifiers, regardless of use, that start with two underscores are reserved. This means they can't be used in header guards. The style that this project is now to use the full name of the file in capital letters followed by 'H'. For example, for a file called "uart_example.h", the header guard is UART_EXAMPLE_H. The exceptions are files that are imported from other projects: - CryptoCell driver - dt-bindings folders - zlib headers Change-Id: I50561bf6c88b491ec440d0c8385c74650f3c106e Signed-off-by: Antonio Nino Diaz

allwinner: Use the arisc to turn off ARM cores

2018-10-20T15:23:59Z

PSCI requires a core to turn itself off, which we can't do properly by just executing an algorithm on that very core. As a consequence we just put a core into WFI on CPU_OFF right now. To fix this let's task the "arisc" management processor (an OpenRISC core) with that task of asserting reset and turning off the core's power domain. We use a handcrafted sequence of OpenRISC instructions to achieve this, and hand this data over to the new sunxi_execute_arisc_code() routine. The commented source code for this routine is provided in a separate file, but the ATF code contains the already encoded instructions as data. The H6 uses the same algorithm, but differs in the MMIO addresses, so provide a SoC (family) specific copy of that code. Signed-off-by: Andre Przywara
