[U-Boot] [PATCH v5 0/8] ARMv7: Add HYP mode switching support
by Andre Przywara 14 Oct '13

14 Oct '13

(for GIT URL and Changelog see below) ARM CPUs with the virtualization extension have a new mode called HYP mode, which allows hypervisors to safely control and monitor guests. The current hypervisor implementations (KVM and Xen) require the kernel to be entered in that HYP mode. This patch series introduces a configuration variable CONFIG_ARMV7_VIRT which enables code to switch all cores into HYP mode. This is done automatically during execution of the bootm command. The process of switching into HYP mode requires the CPU to be in secure state initially when entering u-boot, it will then setup some register and switch to non-secure state. This requires the GIC to be programmed properly first. Explanations about the details are in the commit messages of the respective patches. The patches are structured like this: 1/8: prepare header file 2/8: add monitor handler (assembly) 3/8: add per CPU non-secure switch routine (assembly) 4/8: add system wide non-secure setup (C) 5/8: trigger non-secure switch during bootm command 6/8: add generic SMP functionality 7/8: add HYP mode switching 8/8: board specific code for ARM Versatile Express TC2 Since up to patch 6/8 this code works on non-virtualization capable CPUs also and as there has been a request, there is now a second configuration variable CONFIG_ARMV7_NONSEC, which omits the final HYP mode switch and just goes into non-secure SVC state. You can specify either (or none) of them, the code cares about the dependency. The code aims to be as generic as possible, though currently it has only been tested on the Versatile Express TC-2 board. The last patch thus enables the feature for that board and should serve as an example for supporting other boards. I have had reports from different parties of successful adaptions to other boards as well (Arndale, Cubieboard, Chromebook), so I will create a hypmode-ports branch in the below repository to collect those patches and prepare them for upstreaming. For convenience there is a GIT tree which you can pull these patches from ("hypmode_v5" branch): git://git.linaro.org/people/aprzywara/u-boot.git Changes RFC..v1 * not a dedicated command anymore, code run by bootm & friends * protecting code with #ifdefs to avoid unnecessary inclusion and accidental crashing (when accessing restricted registers) * moving prototypes to header file to meet checkpatch recommendation * adding comment as proposed by Christoffer Changes v1..v2 mostly style and code layout changes * restructure assembly code to live in a new file and not start.S * split smp, nonsec_init and hyp_init to be separate functions * used named constants from common header files * split C function to be more readable * extend comments to be more precise and elaborate * add provision to override GIC base address (needed for Arndale?) * add configuration variable to enable VExpress specific SMP code * use writel/readl for MMIO GIC accesses * remove superfluous isb instructions * more minor fixes Changes v2..v3 * fix clobbering of GICC address actually spoiling the stack * do CNTFRQ setup in assembly per core (and not only once per SoC) * moving the new code files into arch/arm/cpu/armv7 * add config variable for doing non-secure switch only * use actual HYP and secure instructions mnemonics instead of the encoded byte sequence. This requires more recent compilers. * make the identification of the CPU core more robust and saner * use enum for error codes and rename them * lots of smaller layout and style fixes Changes v3..v4 * mask reserved bits in CBAR register * move the VExpress board specific SMP code into the board directory * embed error reporting in the respective functions and getting rid of the error code enum at all (by popular demand ;-) * minor style fixes Changes v4..v5: * remove unneeded padding in exception table * only clear unbanked interrupts in GIC distributor for non-secure * add a default weak implementation for the smp_waitloop() function, there only needs to be provided the address of the SMP pen now * fix compilation error with non-A15 VExpress boards * adding patch specific changelogs for v3..v4 and v4..v5 Please review, comment ... and commit ;-) Contributions and comments to support other boards are welcome.

[U-Boot] [PATCH v3] PCIe:change the method to get the address of a requested capability in configuration space.
by Zhao Qiang 11 Oct '13

11 Oct '13

Previously, the address of a requested capability is define like that "#define PCI_DCR 0x78" But, the addresses of capabilities is different with regard to PCIe revs. So this method is not flexible. Now a function to get the address of a requested capability is added and used. It can get the address dynamically by capability ID. The step of this function: 1. Read Status register in PCIe configuration space to confirm that Capabilities List is valid. 2. Find the address of Capabilities Pointer Register. 3. Find the address of requested capability from the first capability.

[U-Boot] [PATCH] ARM: mxs: Setup stack in JTAG mode
by Marek Vasut 10 Oct '13

10 Oct '13

In case the MX23/MX28 is switched into JTAG mode via the BootMode select switches, the BootROM bypasses the CPU core registers initialization. This in turn means that the Stack Pointer (SP) register is not set as it is in every other mode of operation, but instead is only zeroed out. To prevent U-Boot SPL from crashing in this obscure JTAG mode, configure the SP to point at the CONFIG_SYS_INIT_SP_ADDR if the SP is zeroed out. Note that in case the SP is already configured, we must preserve that exact SP value and must not modify it. This is important since in every other mode but the JTAG mode, the SPL returns into the BootROM and BootROM in turn loads U-Boot itself. If the SP were to be corrupted, the BootROM won't be able to continue it's operation after returned from SPL and the system would crash. Finally, add the JTAG mode switch identifier, so it's not recognised as Unknown mode.

[U-Boot] [PATCH v3] ARM: mxs: tools: Use mkimage for BootStream generation
by Marek Vasut 10 Oct '13

10 Oct '13

Now that mkimage can generate an BootStream for i.MX23 and i.MX28, use the mkimage as a default tool to generate the BootStreams instead of the elftosb tool. This cuts out another obscure dependency.

[U-Boot] [PATCH v2] usb: Prevent using reserved registers on DM36x usb
by Andrew Murray 10 Oct '13

10 Oct '13

The musb driver defines and uses MUSB_CSR0_H_DIS_PING, however this bit is reserved on the DM36x. Thus this patch ensures that the reserved bit is not accesssed. It has been observed that some USB devices will fail to enumerate with errors such as 'error in inquiry' without this patch. See http://www.ti.com/litv/pdf/sprufh9a for details.
