* imx: ventana: config: enable Falcon modeTim Harvey2015-05-21-0/+16

* wandboard: Switch to SPL supportFabio Estevam2015-05-21-10/+17
| | | | | | | | | | | | | | | | | Currently we need to build one U-boot image for each of the wandboard variants: quad, dual-lite and solo. By switching to SPL we can support all these variants with a single binary, which is very convenient. Based on the work from Richard Hu. Tested kernel booting on the three boards.

Return this value as well as min/max temperature based on the value. Note that the IMX6SDLRM and the IMX6SXRM do not indicate this in the their Fusemap Description Table however Freescale has confirmed that these eFUSE bits match the description within the IMX6DQRM and that they will be added to the next revision of the respective reference manuals.

The regulator tests includes: - Regulator get by devname/platname - Voltage set/get - Current set/get - Enable set/get - Mode set/get - Autoset - List autoset For the regulator 'get' test, the returned device pointers are compared, and their names are also compared to the requested one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr serve essentially the same purpose. Roughly, if a command takes a load address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default if the command-line does not specify the address. Different U-Boot commands are inconsistent re: which of the two default values they use. As such, set the two to the same value, and move the logic that does this into tegra-common-post.h so it's not duplicated. A number of other non- Tegra boards do this too. The values chosen for these macros are no longer consistent with anything in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default kernel load address, whereas newer scripts and features tend to use $kernel_addr_r, along with other variables for other purposes such as DTBs and initrds. Hence, it's logical they should share the same value. I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR have different values. This would guarantee no interference if a script used the two variables for different purposes. However, that scenario is unlikely given the semantic meaning associated with the two variables. The lowest available value is 0x90200000; see comments for MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However, that value would be problematic for a script that loaded a raw zImage to $loadaddr, since it's more than 128MB beyond the start of SDRAM, which would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do that. The only potential fallout I could foresee from this patch is if someone has a script that loads the kernel to $loadaddr, but some other file (DTB, initrd) to a hard-coded address that the new value of $loadaddr interferes with. This seems unlikely. A user should not do that; they should either hard-code all load addresses, or use U-Boot-supplied variables for all load addresses. Equally, any fallout due to this change is trivial to fix; simply modify the load addresses in that script.
