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

Merge patch series "Import "string" I/O functions from Linux"

2023-11-28T21:19:19Z

To quote the author: This series imports generic versions of ioread_rep/iowrite_rep and reads/writes from Linux. Some cleanup is done to make sure that all platforms have proper defines for implemented functions and there are no redefinitions.

powerpc: io.h: Add defines for __raw_{read, write} functions

2023-11-28T21:19:06Z

Add defines for __raw_{read,write}{b,w,l}() functions to make make asm-generic/io.h aware of them. Signed-off-by: Igor Prusov

powerpc: Rework includes

2023-11-07T19:50:52Z

This file should not include nor should it include so remove both. Signed-off-by: Tom Rini

powerpc: Switch to

2023-11-07T19:50:51Z

In matching other architectures that have their global_data.h need to bring in a types.h header, switch to on PowerPC. Signed-off-by: Tom Rini

powerpc: use asm-generic/unaligned.h

2023-05-31T18:05:34Z

Powerpc configurations are apparently able to do unaligned accesses. But in an attempt to clean up and handle unaligned accesses in the same way we ignore that and use the common asm-generic/unaligned.h directly instead. Signed-off-by: Jens Wiklander Reviewed-by: Ilias Apalodimas

include: Remove unused header files

2023-05-31T16:31:47Z

As part of various code clean-ups we have on occasion missed removing unused header files. None of these files are referenced anywhere else at this point. Signed-off-by: Tom Rini

powerpc: mpc885: Add CPM USB-SOF microcode for CPM15 ERRATA

2023-05-05T05:26:53Z

MPC885 CPU has the following ERRATA: When the USB controller is configured in Host mode, and the SOF generation (SFTE=1 in USMOD register) is being used, there may be false CRC error indication in other SCCs. Although the data is received correctly, the CRC result will be corrupted. Add capability to load the related microcode to fix it. The microcode binary data is copied from Linux kernel. Other microcode will be added in following patch so make it a Kconfig choice. Signed-off-by: Christophe Leroy

powerpc: Force cast on memcpy_toio()

2023-05-05T05:26:53Z

sparse reports the following warning: CHECK arch/powerpc/cpu/mpc8xx/micropatch_usb_sof.c arch/powerpc/cpu/mpc8xx/micropatch_usb_sof.c:29:9: warning: cast removes address space '' of expression arch/powerpc/cpu/mpc8xx/micropatch_usb_sof.c:30:9: warning: cast removes address space '' of expression This is because of (void *) casts for using memcpy() as a substitute. Do like other architectures, __force the cast to silence the warning Signed-off-by: Christophe Leroy

powerpc: mpc8xx: Reorganise init RAM

2023-05-04T10:40:47Z

Using SMC relocation microcode patch or USB-SOF microcode patch will disable DPRAM memory from 0x2000 to 0x2400 and from 0x2f00 to 0x3000. At the time being, init RAM is setup to use 0x2800-0x2e00, but the stack pointer goes beyond 0x2800 and even beyond 0x2400. For the time being we are not going to use any microcode patch that uses memory about 0x3000, so reorganise setup to use: - 0x2800 - 0x2e00 for init malloc and global data and CPM buffers - 0x3000 - 0x3c00 for init stack For more details about CPM dual port ram, see commit b1d62424cb ("powerpc: mpc8xx: redistribute data in CPM dpram") Signed-off-by: Christophe Leroy
