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

powerpc: mpc8xx: CPM parameter RAM can be anywhere

2023-05-04T08:58:07Z

With relocation, CPM parameter RAM can be anywhere in the dual port RAM, so don't split dual port RAM. Remove dparam and dparam16 members of struct comm_proc PROFF_XXX become offsets from the start of dual port RAM, then they are now consistant with the offsets in RPBASE registers.

spi: mpc8xxx: Add support for SPI on mpc832x

2023-04-06T12:50:03Z

On mpc832x, SPI can be either handled by CPU or QE. In order to work in CPU mode, bit 17 of SPMODE has to be set to 1, that bit is called OP. Also, data is located at a different place than the one expected by the driver today. In 8 bits mode with REV set, data to be transmitted is located in the most significant byte while received data is located in second byte. So perform the necessary shifts. In order to differentiate with other CPUs, a new compatible is added for mpc832x: fsl,mpc832x-spi Signed-off-by: Christophe Leroy Cc: Rasmus Villemoes

gpio: Add QUICC Engine GPIOs driver

2023-04-06T12:50:03Z

The mpc832x has GPIOs handled by the QUICC Engine. The registers are different from the one for the non QE mpc83xx GPIOs. Implement a GPIO driver for those. Signed-off-by: Christophe Leroy

powerpc: mpc83xx: Fix soc.h

2023-04-06T12:50:03Z

There are helpers included in soc.h Declare them static inline so that soc.h can be included in several places. Signed-off-by: Christophe Leroy

driver, gpio: Add support for MPC 8xx CPU ports

2023-02-11T07:47:58Z

Ports A, C and D are 16 bits ports. Ports B and E are 32 bits ports. The "compatible" is used to determine each port type. This patch was originally written by Charles Frey who's email address is not valid anymore as he left the company. Signed-off-by: Christophe Leroy Reviewed-by: FRANJOU Stephane
