global: Rework architecture global_data.h to include

2023-12-21T13:54:37Z

In most cases, the architecture global data currently makes use of assorted linux types, but does not include to provide them. Add instead of relying on indirect inclusion. Reviewed-by: Simon Glass Signed-off-by: Tom Rini

mips: global_data.h: Add Octeon specific data to arch_global_data struct

2021-04-23T19:02:12Z

This will be used by the upcoming Serdes and driver code ported from the original 2013 U-Boot code to mainline. Signed-off-by: Stefan Roese

mips: add a mtmips-specific field to architecture-specific global data

2020-04-27T18:29:33Z

SoCs of mtmips can use different CPU frequencies depending on the HW/SW configurations. For example mt7628 uses 580MHz clock if the input xtal frequency is 40MHz, and 575MHz clock if the xtal is 25MHz. Upon cold boot the CPU uses the xtal frequency directly. So hardcoding the timer frequency (half of the CPU frequency) in CONFIG_SYS_MIPS_TIMER_FREQ is not a good idea for this case. This patch adds a mtmips-specific field timer_freq to arch_global_data. This field will be used later in mtmips-specific get_tbclk() to provide accurate timer frequency in different boot stage.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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

MIPS: L2 cache support

2016-09-21T13:04:04Z

This patch adds support for initialising & maintaining L2 caches on MIPS systems. The L2 cache configuration may be advertised through either coprocessor 0 or the MIPS Coherence Manager depending upon the system, and support for both is included. If the L2 can be bypassed then we bypass it early in boot & initialise the L1 caches first, such that we can start making use of the L1 instruction cache as early as possible. Otherwise we initialise the L2 first such that the L1s have no opportunity to generate access to the uninitialised L2. Signed-off-by: Paul Burton

MIPS: Probe cache line sizes once during boot

2016-09-21T13:04:04Z

Rather than probing the cache line sizes on every call of any cache maintenance function, probe them once during boot & store the values in the global data structure for later use. This will reduce the overhead of the cache maintenance functions, which isn't a big deal yet but becomes more important once L2 caches which may expose their properties via coprocessor 2 or the CM are supported.

MIPS: Support dynamic I/O port base address

2016-02-01T21:13:25Z

The existing mips_io_port_base variable isn't suitable for use early during boot since it will be stored in the .data section which may not be writable pre-relocation. Fix this by moving the I/O port base address into struct arch_global_data. In order to avoid adding this field for all targets, make this dependant upon a new Kconfig entry CONFIG_DYNAMIC_IO_PORT_BASE. Malta is the only board which sets a non-zero I/O port base, so select this option only for Malta. Signed-off-by: Paul Burton
