[U-Boot] [PATCH] pxe: implement fdtdir extlinux.conf tag
by Stephen Warren 24 Jan '14

24 Jan '14

From: Stephen Warren <swarren(a)nvidia.com> People who write (or scripts that auto-generate) extlinux.conf don't want to know about HW-specific information such as FDT filenames. Create a new extlinux.conf tag "fdtdir" that specifies only the directory where FDT files are located, and defer all knowledge of the filename to U-Boot. The algorithm implemented is: ========== if $fdt_addr_r is set: if "fdt" tag was specified in extlinux.conf: load the FDT from the filename in the tag else if "fdtdir" tag was specified in extlinux.conf: if "fdtfile" is set in the environment: load the FDT from filename in "$fdtfile" else: load the FDT from some automatically generated filename if no FDT file was loaded, and $fdtaddr is set: # This indicates an FDT packaged with firmware use the FDT at $fdtaddr ========== A small part of an example /boot/extlinux.conf might be: ========== LABEL primary LINUX zImage FDTDIR ./ LABEL failsafe LINUX bkp/zImage FDTDIR bkp/ ========== ... with /boot/tegra20-seaboard.dtb or /boot/bkp/tegra20-seaboard.dtb being loaded by the sysboot/pxe code.

[U-Boot] [PATCH V3] ARM: tegra: don't exceed AVP limits when configuring PLLP
by Stephen Warren 24 Jan '14

24 Jan '14

From: Jimmy Zhang <jimmzhang(a)nvidia.com> Based on the Tegra TRM, the system clock (which is the AVP clock) can run up to 275MHz. On power on, the default sytem clock source is set to PLLP_OUT0. In function clock_early_init(), PLLP_OUT0 will be set to 408MHz which is beyond system clock's upper limit. The fix is to set the system clock to CLK_M before initializing PLLP, and then switch back to PLLP_OUT4, which has an appropriate divider configured, after PLLP has been configured Implement this logic in new function tegra30_set_up_pllp(), which sets up PLLP and all PLLP_OUT* dividers, and handles the AVP clock switching. Remove the duplicate PLLP setup from pllx_set_rate() and adjust_pllp_out_freqs().

[U-Boot] [PATCH V2] ARM: tegra: don't exceed AVP limits when configuring PLLP
by Stephen Warren 24 Jan '14

24 Jan '14

From: Jimmy Zhang <jimmzhang(a)nvidia.com> Based on the Tegra TRM, the system clock (which is the AVP clock) can run up to 275MHz. On power on, the default sytem clock source is set to PLLP_OUT0. In function clock_early_init(), PLLP_OUT0 will be set to 408MHz which is beyond system clock's upper limit. The fix is to set the system clock to CLK_M before initializing PLLP, and then switch back to PLLP_OUT4, which has an appropriate divider configured, after PLLP has been configured Implement this logic in new function tegra30_or_later_adjust_pllp(), which sets up PLLP and all PLLP_OUT* dividers, and handles the AVP clock switching. Remove the duplicate PLLP setup from pllx_set_rate() and adjust_pllp_out_freqs().

[U-Boot] [PATCH V2] ARM: tegra: amend pmc.h for Tegra114+
by Stephen Warren 24 Jan '14

24 Jan '14

From: Stephen Warren <swarren(a)nvidia.com> Tegra114 and later's PMC module removes the pwrgate_timer_on register and replaces it with a clamp_status register. Adjust pmc.h to reflect this, and update any code affected by the change. The cpu.c change in this patch was extracted from a much larger patch by Jimmy Zhang. The pmc.h change was written from scratch, but inspired by related changes made by Tom Warren. There could well be other differences in the PMC register set for chips after Tegra20/30. However, they don't affect the code in U-Boot at present, so I haven't attempted an exhaustive update of pmc.h.

[U-Boot] [PATCH V2 1/6] ARM: tegra: deduplicate MASK_BITS_xxx clock mux enum
by Stephen Warren 24 Jan '14

24 Jan '14

From: Tom Warren <twarren.nvidia(a)gmail.com> The enum used to define the set of register bits used to represent a clock's input mux, MUX_BITS_*, is defined separately for each SoC at present. Move this definition to a common location to ease fixing up some issues with the definition, and the code that uses it.

That's already fixed in the V2 of the patches (see the patchwork link I posted). Best regards, Marek Vasut
