[U-Boot] [PATCH] thermal: imx_thermal: increase critical temperature threshold
by Tim Harvey 26 May '15

26 May '15

The CPU temperature grade from OTP is now used to define the critical threshold at which point we busyloop until we are below, however this threshold is still too low. Instead of 20C below the max CPU temperature, change it to 5C defined now by TEMPERATURE_HOT_DETLA for clarity. Rename 'passive' to 'critical' as that better defines our use case here. Additionally change the output of the busyloop message to show the max CPU temperature as well as current. Before: CPU Temperature is 101 C, too hot to boot, waiting... CPU Temperature is 101 C, too hot to boot, waiting... After: CPU Temperature (101C) too close to max (105C) waiting... CPU Temperature (101C) too close to max (105C) waiting...

We should not hardcode MXS_DMA_ALIGNMENT to 32, since we can not guarantee that socs' cache line size is 32 bytes. If on chips whose cache line size is 64 bytes, error occurs: " NAND: ERROR: v7_dcache_inval_range - start address is not aligned - 0xbdf1d1a0 ERROR: v7_dcache_inval_range - stop address is not aligned - 0xbdf1f4a0 ERROR: v7_dcache_inval_range - start address is not aligned - 0xbdf1d1a0 " Align MXS_DMA_ALIGNMENT with ARCH_DMA_MINALIGN whose value is same to CONFIG_SYS_CACHELINE_SIZE if CONFIG_SYS_CACHELINE_SIZE defined.

[U-Boot] Generic Board for SPARC ?
by Masahiro Yamada 26 May '15

26 May '15

Hi, The patch series for SPARC generic board was posted last November, but it has been dismissed so far (and it cannot be applied to the mainline any more.) http://patchwork.ozlabs.org/patch/406966/ It has been delegated to Daniel Hellstrom, but it looks like he has been inactive for more than one year. Daniel, I hope your response if this message reaches you. -- Best Regards Masahiro Yamada

Re: [U-Boot] U-boot qemu-x86 :load acpi tables from fw_cfg.

It is being used by q-boot, a new minimal x86 firmware for QEMU. http://lwn.net/Articles/645455/ https://github.com/bonzini/qboot q-boot is able to give a minimal booting time, with the help of fw_cfg, by reading both the kernel and initrd image from fw_cfg. I guess ACPI support for both q-boot and qemu-x86 in u-boot can be implemented on similar lines. Regards, Saket Sinha
