2021-06-16arm64: dts: ti: k3-am64-main: Update TF-A's maximum size and node nameAswath Govindraju1-2/+2
The maximum size of TF-A 2.5 has been increased to 0x1c000 [1]. In order to account for future expansions too, increase the allocated size for TF-A to 0x20000, in the device tree node. Also, update the node name to "tfa-sram".

It's not worth duplicating the same node over and over and over and over again, so let's keep the common bits in the pm8150 DTSI, making only changing the status and keycode necessary.

2021-06-15arm64: dts: qcom: sm8250: Add support for SONY Xperia 1 II / 5 II (Edo platform)Konrad Dybcio4-0/+566
Add support for SONY Xperia 1 II and 5 II smartphones (read one/five mark two). They are based on the Qualcomm SM8250 chipset and both feature 5G modems. There also exists a third Edo board, namely the Xperia PRO (PDX204), but it's $2500 and no developers have obtained it so far (to my knowledge). The devices are affected by a scary UFS behaviour where sending a certain UFS command (which is worked around on downstream) renders the device unbootable, by effectively erasing the bootloader. Therefore UFS AND UFSPHY are strictly disabled for now.

2021-06-15arm64: dts: qcom: sm8250: Move gpio.h inclusion to SoC DTSIKonrad Dybcio3-2/+1
Almost any board that boots and has a way to interact with it (say for the rare cases of just-pstore or let's-rely-on-bootloader-setup) needs to set some GPIOs, so it makes no sense to include gpio.h separately each time. Hence move it to SoC DTSI.

Add support for SONY Xperia 1 and 5 smartphones, both based on the Qualcomm SM8150 chipset. There also exist 5G-capable versions of these devices, but they weren't sold much (if at all) outside Japan. The devices are affected by a scary UFS behaviour where sending a certain UFS command (which is worked around on downstream) renders the device unbootable, by effectively erasing the bootloader.

2021-06-15arm64/mm: Fix ttbr0 values stored in struct thread_info for software-panAnshuman Khandual2-3/+3
When using CONFIG_ARM64_SW_TTBR0_PAN, a task's thread_info::ttbr0 must be the TTBR0_EL1 value used to run userspace. With 52-bit PAs, the PA must be packed into the TTBR using phys_to_ttbr(), but we forget to do this in some of the SW PAN code. Thus, if the value is installed into TTBR0_EL1 (as may happen in the uaccess routines), this could result in UNPREDICTABLE behaviour. Since hardware with 52-bit PA support almost certainly has HW PAN, which will be used in preference, this shouldn't be a practical issue, but let's fix this for consistency.

2021-06-15arm64: mm: Pass original fault address to handle_mm_fault()Gavin Shan1-1/+1
Currently, the lower bits of fault address is cleared before it's passed to handle_mm_fault(). It's unnecessary since generic code does same thing since the commit 1a29d85eb0f19 ("mm: use vmf->address instead of of vmf->virtual_address"). This passes the original fault address to handle_mm_fault() in case the generic code needs to know the exact fault address.

SECTION_[SHIFT|SIZE|MASK] are essentially PMD_[SHIFT|SIZE|MASK]. But these create confusion being similar to generic sparsemem memory sections, which are derived from SECTION_SIZE_BITS. Section references have always implied PMD level block mapping. Instead just use all PMD level macros which would make it explicit and also remove confusion with sparsmem memory sections.

2021-06-15arm64: Conditionally configure PTR_AUTH key of the kernel.Daniel Kiss5-47/+67
If the kernel is not compiled with CONFIG_ARM64_PTR_AUTH_KERNEL=y, then no PACI/AUTI instructions are expected while the kernel is running so the kernel's key will not be used. Write of a system registers is expensive therefore avoid if not required.

2021-06-14CFI: Move function_nocfi() into compiler.hMark Rutland2-16/+16
Currently the common definition of function_nocfi() is provided by <linux/mm.h>, and architectures are expected to provide a definition in <asm/memory.h>. Due to header dependencies, this can make it hard to use function_nocfi() in low-level headers. As function_nocfi() has no dependency on any mm code, nor on any memory definitions, it doesn't need to live in <linux/mm.h> or <asm/memory.h>. Generally, it would make more sense for it to live in <linux/compiler.h>, where an architecture can override it in <asm/compiler.h>. Move the definitions accordingly.

8250_omap compatible UART IPs on all SoCs have registers aligned at 4 byte address boundary and constant byte addressability. Thus there is no need for reg-io-width or reg-shift DT properties. These properties are not used by 8250_omap driver nor documented as part of binding document. Therefore drop them. This is in preparation to move omap-serial.txt to YAML format.

2021-06-14arm64: dts: ti: k3-am642-main: fix ports mac propertiesGrygorii Strashko1-2/+3
The current device tree CPSW3g node adds non-zero "mac-address" property to the ports, which prevents random MAC address assignment to network devices if bootloader failed to update DT. This may cause more then one host to have the same MAC in the network. mac-address = [00 00 de ad be ef]; mac-address = [00 01 de ad be ef]; In addition, there is one MAC address available in eFuse registers which can be used for default port 1. Hence, fix ports MAC properties by: - resetting "mac-address" property to 0 - adding ti,syscon-efuse = <&main_conf 0x200> to Port 1 Fixes: 3753b12877b6 ("arm64: dts: ti: k3-am64-main: Add CPSW DT node") Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Reviewed-by: Vignesh Raghavendra <vigneshr@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Link: https://lore.kernel.org/r/20210608184940.25934-1-grygorii.strashko@ti.com
