* ARM: boards: phytec-som-am335x: Revert unified MLO for 1GBDaniel Schultz2018-01-051-0/+1
| | | | | | | | | | | There is a problem in the data path between 1GB RAM devices and the core, which leads to wrong read operations after DDR initialization in soft resets. This needs more investigation, but until we didn't found the problem, we will return to the origin MLO for 1GB RAM devices with static RAM timings and without memory access.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using "ifup ethx" use "ifup -a" which works with all network interfaces. Also replace "$ethx.serverip" with "$global.net.server". This makes the automount independent of the actual network interface. Remove all board specific /env/init/automount files which were only there to use eth1 instead of the previously hardcoded eth0. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | net: dhcp: reworkSascha Hauer2017-12-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DHCP code is a mess. It is not clear which options are sent to the server and which options are returned from the server. Also environment variables are read from and written to all over the place. This patch cleans this up. There now is struct dhcp_req_param which is used for options sent to the server and struct dhcp_result which contains the values sent from the server. The values from the server are written to the barebox variables in a single place. Also it's now possible to call the dhcp code without modifying barebox variables at all, storing the result only in the dhcp result struct. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

It seems that barebox does not have a driver for brcm,bcm2835-sdhost (yet), which resulted in barebox unable to boot from SD card. However, the driver for brcm,bcm2835-sdhci worked fine in the past. Although the upstream change was made for good reasons, the simplest change for barebox for now is to revert to using &sdhci and disable &sdhost.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PCM-060 modules only have one-bank RAMs populated, which allows us to find out the populated RAM size at run-time. Therefore, a new entry point was create 'PHYTEC_ENTRY_UNIFIED_MLO'. This creates a MLO for all modules of one family and all existing PCM-060 MLOs were replaced with this new entry point. To provide backward compatibility for older modules, these were not affected. In the first step generic RAM timings for the module family get loaded, because RAM accesses are only possible with an initialized controller. After that, the RAM size will be calculated and the RAM controller gets reinitialized with the correct RAM timings.

As on i.MX25 the HW default is active high and up to now barebox didn't force this to low (which is the default for e.g. i.MX6), add the property to barebox' imx25.dtsi to keep existing behaviour. If on a board the OC pin is active low, you need to add /delete-property/ over-current-active-high; in the board.dts.
