2021-02-06media: mach-pxa: Register the camera sensor fixed-rate clockEzequiel Garcia1-0/+8
The pxa-camera capture driver currently registers a v4l2-clk clock, named "mclk", to represent the mt9m111 sensor clock. Register a proper fixed-rate clock using the generic clock framework, which will allow to remove the v4l2-clk clock in the pxa-camera driver in a follow-up commit.

2021-02-05ARM: kexec: fix oops after TLB are invalidatedRussell King4-39/+36
Giancarlo Ferrari reports the following oops while trying to use kexec: Unable to handle kernel paging request at virtual address 80112f38 pgd = fd7ef03e [80112f38] *pgd=0001141e(bad) Internal error: Oops: 80d [#1] PREEMPT SMP ARM ... This is caused by machine_kexec() trying to set the kernel text to be read/write, so it can poke values into the relocation code before copying it - and an interrupt occuring which changes the page tables. The subsequent writes then hit read-only sections that trigger a data abort resulting in the above oops. Fix this by copying the relocation code, and then writing the variables into the destination, thereby avoiding the need to make the kernel text read/write.

2021-02-03ARM: dts: meson: add the AO ARC remote processorMartin Blumenstingl3-0/+49
The 32-bit Amlogic Meson SoCs embed an ARC processor in the Always-On power domain which is typically used for managing system suspend. The memory for this ARC core is taken from the AHB SRAM area. Depending on the actual SoC a different ARC core is used: - Meson6 and earlier: some ARCv1 ISA based core (probably an ARC625) - Meson8 and later: an ARC EM4 (ARCv2 ISA) based core Add the device-tree node for this remote-processor along with the required SRAM sections, clocks and reset-lines. Also use the SoC-specific compatible string to manage any differences (should they exist). On Meson8, Meson8b and Meson8m2 the "secbus2" IO region is needed as some bits need to be programmed there. Add this IO region for those SoCs as well.

2021-02-03ARM: dts: lpc32xx: Revert set default clock rate of HCLK PLLAlexandre Belloni1-3/+0
This reverts commit c17e9377aa81664d94b4f2102559fcf2a01ec8e7. The lpc32xx clock driver is not able to actually change the PLL rate as this would require reparenting ARM_CLK, DDRAM_CLK, PERIPH_CLK to SYSCLK, then stop the PLL, update the register, restart the PLL and wait for the PLL to lock and finally reparent ARM_CLK, DDRAM_CLK, PERIPH_CLK to HCLK PLL. Currently, the HCLK driver simply updates the registers but this has no real effect and all the clock rate calculation end up being wrong. This is especially annoying for the peripheral (e.g. UARTs, I2C, SPI).

2021-02-01ARM: 9050/1: Kconfig: Select ARCH_HAVE_NMI_SAFE_CMPXCHG where possibleDaniel Thompson1-0/+1
Currently ARCH_HAVE_NMI_SAFE_CMPXCHG is not set on Arm systems and this makes it impossible to enable features such as ftrace histogram triggers on Arm platforms. Most Arm systems are NMI safe simply because there is no NMI but this isn't universally true meaning we cannot set ARCH_HAVE_NMI_SAFE_CMPXCHG for all Arm devices. However the load/store exclusive implementation of cmpxchg is NMI-safe and this implementation is used ARMv6k and later. Let's select ARCH_HAVE_NMI_SAFE_CMPXCHG for these systems. Note that ARMv6 uses load/store exclusive for 32-bit cmpxchg but relies on interrupt masking for 8- and 16-bit operations. This patch is conservative and does not change behaviour for CPU_V6.

2021-02-01ARM: 9046/1: decompressor: Do not clear SCTLR.nTLSMD for ARMv7+ coresVladimir Murzin1-2/+2
It was observed that decompressor running on hardware implementing ARM v8.2 Load/Store Multiple Atomicity and Ordering Control (LSMAOC), say, as guest, would stuck just after: Uncompressing Linux... done, booting the kernel. The reason is that it clears nTLSMD bit when disabling caches: nTLSMD, bit [3] When ARMv8.2-LSMAOC is implemented: No Trap Load Multiple and Store Multiple to Device-nGRE/Device-nGnRE/Device-nGnRnE memory. 0b0 All memory accesses by A32 and T32 Load Multiple and Store Multiple at EL1 or EL0 that are marked at stage 1 as Device-nGRE/Device-nGnRE/Device-nGnRnE memory are trapped and generate a stage 1 Alignment fault. 0b1 All memory accesses by A32 and T32 Load Multiple and Store Multiple at EL1 or EL0 that are marked at stage 1 as Device-nGRE/Device-nGnRE/Device-nGnRnE memory are not trapped. This bit is permitted to be cached in a TLB. This field resets to 1. Otherwise: Reserved, RES1 So as effect we start getting traps we are not quite ready for. Looking into history it seems that mask used for SCTLR clear came from the similar code for ARMv4, where bit[3] is the enable/disable bit for the write buffer. That not applicable to ARMv7 and onwards, so retire that bit from the masks.

2021-02-01ARM: 9045/1: uncompress: Validate start of physical memory against passed DTBGeert Uytterhoeven4-7/+172
Currently, the start address of physical memory is obtained by masking the program counter with a fixed mask of 0xf8000000. This mask value was chosen as a balance between the requirements of different platforms. However, this does require that the start address of physical memory is a multiple of 128 MiB, precluding booting Linux on platforms where this requirement is not fulfilled. Fix this limitation by validating the masked address against the memory information in the passed DTB. Only use the start address from DTB when masking would yield an out-of-range address, prefer the traditional method in all other cases. Note that this applies only to the explicitly passed DTB on modern systems, and not to a DTB appended to the kernel, or to ATAGS. The appended DTB may need to be augmented by information from ATAGS, which may need to rely on knowledge of the start address of physical memory itself. This allows to boot Linux on r7s9210/rza2mevb using the 64 MiB of SDRAM on the RZA2MEVB sub board, which is located at 0x0C000000 (CS3 space), i.e. not at a multiple of 128 MiB.

2021-02-01ARM: 9042/1: debug: no uncompress debugging while semihostingLinus Walleij1-1/+1
The build robots have discovered that uncompress debugging and semihosting does not play well together. This is due to many factors but in general semihosting debug needs to be rewritten to work the same way as any LL_DEBUG, e.g. with a header in arch/arm/include/debug/semihosting.S This is a long term solution and needs testing on real hardware and/or software models using semihosting. For now disable uncompress debugging under semihosting.
