| * | net: smc1111: extend the driver for 91c94 and 91c96 supportRobert Jarzmik2015-02-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the smcs family chips 91c94, 91c96, 91c100, 91c111 share almost the same behavior and register sets. The noticeable exceptions are coped with in this patch, ie : - 91c94 and 91c96 only have an internal 10 Mbps phy The registers used for phy discovery on later chips will corrupt the 91c96 state. - 91c94 and 91c96 have a control and config register quite different from their 91c1xx conterparts A platform data user defined couple of registers is introduced. If these values are 0, 91c1xx legacy behavior is assumed. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | net: smc1111: add 16 bits accessors, allow address shiftRobert Jarzmik2015-02-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Smc network IPs can be wired up in different funny ways. For example the lubbock pxa25x development platform wires all address lines shifted by 2, ie. bus A2 is smc91c96 A0, bus A3 is smc91c96 A1 etc ... In order to cope with the different possible combination, add a shift parameter for addresses. By default, the old behaviour using the 32 bit accesses is kept.

| * | mtd: nand: add mrvl-nand driverRobert Jarzmik2015-01-191-0/+79
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver is taken from the Linux kernel, with the following changes : - all DMA removed - all asynchronous handling removed, including the interrupt handler, and the asynchronous state handling - pxa armada support removed Most the kernel structure was kept, to ease up future fixes integration from the kernel driver. The driver is tested on a pxa3xx system development board (aka. zylonite), and reading, writing, erasing, and bad block management were tested.

* / ARM: i.MX6: use generic calculation in nand bbu handlerStefan Christ2015-01-291-0/+37

Instead of hardcoding these values into the imx6 bbu handler calculate these values on the fly. Therefore we export the necessary functions from the nand_mxs driver to use them in the bbu handler.

For now puts_ll is used to print the messages, so it depends on CONFIG_DEBUG_LL which makes it more a debugging option. However, this could be extended later to get regular output from the PBL if desired. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds (back) support for non volatile variables. Non volatile variables are variables which are stored in the environment over reboot. They are used in the same way as the global variables, but with a 'nv' command and device. The variables are stored under /env/nv/, one variable per file. Adding a nv variable automatically adds a global variable with the same name. Changing a nv variable also changes the same global variable, but not the other way round. This allows for example to configure the username as: nv user=sha; saveenv Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
