* mtd: partition: Fix OF partition fixupSascha Hauer2015-04-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To get the number of address cells and size cells we have to use the newly created partition node, not the parent device node. The parent device node returns the address/size cells of the controller node, not the partition node. On an am335x machine this fixes the device tree passed to Linux. The situation there is: ... gpmc@50000000 { ... #address-cells = <0x2>; #size-cells = <0x1>; ranges = <0x0 0x0 0x8000000 0x10000000>; ... nand@0,0 { reg = <0x0 0x0 0x0>; #address-cells = <0x1>; #size-cells = <0x1>; ... partition@7 { label = "system"; reg = <0x220000 0x7de0000>; }; }; }; and without this patch barebox passes three bytes for partition@7's reg property instead of only two which naturally confuses Linux and yields to the system partition to start at 0 with a size of 0x220000.

| * state: add framework for persistent state handlingSascha Hauer2015-03-123-0/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a framework to describe, access, store and restore a set of variables. A state variable set can be fully described in a devicetree node. This node could be part of the regular devicetree blob or it could be an extra devicetree solely for the state. The state variable set contains variables of different types and a place to store the variable set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As hinted in the linux kernel driver, pxa platforms such as mainstone, stargate and idp have a broken design, where half-word writes not aligned to a word address are not working. This patch is a taking back the half-word write accessor for this specific case from the linux kernel.

The driver looks in parts quite similar to the kernel driver, I don't know whether one is derived from the other or if they both just have the same origin. Many coding style related issues are fixed, the code is simplified in several places. All features of the original driver should still be there, only fiber support is disabled since it's quite unlikely that this is used in barebox. The driver has been tested with the i.MX6 PCIe driver and a I210 e1000 device (0x8086:0x1533) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
