| | | | | | | | | | | | | | We have a number of sama5d3 devices that sometimes hangs at the barebox prompt during boot due to floating RX pins. This patch fixes the problem for us (and probably others). It is similar in nature to linux kernel commit 138c2b2f175b ("ARM: dts: at91: fixes dbgu pinctrl, set pullup on rx, clear pullup on tx") While at it, remove pointless waste of power that the pullup of the TX pins causes and fix the signal comments for SAMA5D4.

* bootstrap: Boot barebox with kernel calling conventionTrent Piepho2015-12-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | In commit 8e3ddc13eb8239177ed20f119e3a3d02518b941d the bootm code was changed to boot barebox using the same calling convention as the kernel. Which on ARM is to pass three arguments which are zero, an architecture code, and a params pointer. A 2nd stage barebox can be booted using lib/bootstrap, which is different code from bootm. This code just leaves garbage in the first three parameters and so doesn't follow the convention. Change it to be compatible with the ARM kernel booting convention. This just sends a zero for the architecture, since the code for architectures depends on boot[zmu] and something using bootstrap wouldn't have those too. And it just passes NULL for the params since we don't have a way to pass a device tree from the preloader. All users of bootstrap are ARM based, but the code is in lib so a non-ARM board might someday make use of it. If the current code would work for them, then the change here will be ok too.

* at91sam9x5: fix ROM base address (bugfix for nand ECC)iEdoardo Scaglia2015-10-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The ROM base address in the 9x5 processors lives at 1M, not 4M, where SMD is, as defined later in the same file. The ROM includes some tables that are used to build error-correction data for NAND memory. By using the wrong address, we get wrong data and the result is undetected bit flips (data at 0x408000 is all zeroes). Thus, even though our kernel was fixing bit errors in NAND, barebox was not fixing them. With UBI (our situation) we got I/O errors because the checksum verification for data nodes failed. Using the proper address corrects the problem: barebox reports a "bitflip" message, consistent with the kernel message for the same file, and the files are properly loaded and booted. Note: the kernel has the same wrong define, but then the magic number 0x00108000 as spelled in arch/arm/boot/dts/at91sam9x5.dtsi is used instead of the symbolic name.

| * restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-275-8/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.
