* drivers: hierarchize drivers Kconfig menuMasahiro Yamada2015-08-1211-0/+68
| | | | | | | | | | | The menuconfig for drivers are getting more and more cluttered and unreadable because too many entries are displayed in a single flat menu. Use hierarchic menu for each category.

| | | | | | | | | | | This allows scanning the twl4030 keypad, storing the result in a 64-byte long matrix with the twl4030_keypad_scan function.

| | | | | | | | | | This adds support for powering off (the omap3 SoC) from the twl4030. This is especially useful when the kernel does not actually power off the device using this method but reboots and leaves it up to the bootloader to actually turn the power off.

* nand: lpc32xx: add SLC NAND controller supportVladimir Zapolskiy2015-08-122-0/+177
| | | | | | | | | | | | | | | | | | | | | The change adds support of LPC32xx SLC NAND controller. LPC32xx SoC has two different mutually exclusive NAND controllers to communicate with single and multiple layer chips. This simple driver allows to specify NAND chip timings and defines custom read_buf()/write_buf() operations, because access to 8-bit data register must be 32-bit aligned. Support of hardware ECC calculation is not implemented (data correction is always done by software), since it requires a working DMA engine. The driver can be included to an SPL image.

* spl: nand: simple: replace readb() with chip specific read_buf()Vladimir Zapolskiy2015-08-121-2/+5
| | | | | | | | | | | | | | | Some NAND controllers define custom functions to read data out, respect this in order to correctly support bad block handling in simple SPL NAND framework. NAND controller specific read_buf() is used even to read 1 byte in case of connected 8-bit NAND device, it turns out that read_byte() may become outdated.

| * dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial portHans de Goede2015-08-102-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB devices are not really designed to get the power bounced off and on at them. Esp. USB powered harddisks do not like this. Currently we power off the USB ports both on a "usb reset" and when booting the kernel, causing the usb-power to bounce off and then back on again. This patch removes the powering off calls, fixing the undesirable power bouncing. Note this requires some special handling for the OTG port: 1) We must skip the external vbus check if we've already enabled our own vbus to avoid false positives 2) If on an usb reset we no longer detect that the id-pin is grounded, turn off vbus as that means an external vbus may be present now Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

* | ddr: altera: sdram: Make sdram_start and sdram_end into u32Marek Vasut2015-08-081-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, both sdram_start and sdram_end were 64b values. The sdram_start had no reason for being so, since our address space is only 32b, so switching sdram_start to u32 is simple. The sdram_end is a bit more complex, since it can actually be set to (1 << 32) if someone really wanted to use an SoCFPGA with 4 GiB of DRAM and fixed the code around a little. But, the code handling the protection rules internally decrements the sdram_end variable anyway. Thus, instead of calling the code and passing in the address of the SDRAM end, pass in the address already decremented by one. This lets the sdram_end be 32b as well.
