* net: designware: Rename the driver var name to eth_designwareMarek Vasut2015-08-08-1/+1

* arm: dts: socfpga: Fix SPI aliasesMarek Vasut2015-08-08-16/+5
| | | | | | | | | | | | | The SPI aliases are completely wrong. First, they point to non-existing /spi@.* nodes instead of the correct /soc/spi@.* nodes. Second, the use ad-hoc string instead of a handle. Furthermore, they are copied multiple times in each board DTS. So fix it such that we move these into socfpga.dtsi and make them use the usual handles. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Dinh Nguyen <dinguyen@opensource.altera.com>

| | | | | | | | | | | | | | | | At present lower case is used for the regulator names in the device tree. The kernel uses upper case and U-Boot will require this also since it will move to a case-sensitive name check. Signed-off-by: Simon Glass <sjg@chromium.org>
| * x86: Enable debug UART for MinnowmaxSimon Glass2015-08-06-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable the debug UART and emit a single 'a' early in the init sequence to show that it is working. Unfortunately the debug UART implementation needs a stack to work. I cannot seem to remove this limitation as the absolute 'jmp %eax' instruction goes off into the weeds. So this means that the character output cannot be any earlier than car_init_ret, where memory is available for a stack.

| * dm: core: Add a way to set a device nameSimon Glass2015-08-06-0/+25
| | | | | | | | | | | | | | | | | | | | Some devices are bound entirely by probing and do not have the benefit of a device tree to give them a name. This is very common with PCI and USB. In most cases this is fine, but we should add an official way to set a device name. This should be called in the device's bind() method.

| * devres: add debug command to dump device resourcesMasahiro Yamada2015-08-06-2/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new command can dump all device resources associated to each device. The fields in every line shows: - The address of the resource - The size of the resource - The name of the release function - The stage in which the resource has been acquired (BIND/PROBE) Currently, there is no driver using devres, but if such drivers are implemented, the output of this command should look like this: => dm devres - root_driver - soc - extbus - serial@54006800 bfb541e8 (8 byte) devm_kmalloc_release BIND bfb54440 (4 byte) devm_kmalloc_release PROBE bfb54460 (4 byte) devm_kmalloc_release PROBE - serial@54006900 bfb54270 (8 byte) devm_kmalloc_release BIND - gpio@55000000 - i2c@58780000 bfb5bce8 (12 byte) devm_kmalloc_release PROBE bfb5bd10 (4 byte) devm_kmalloc_release PROBE - eeprom bfb54418 (12 byte) devm_kmalloc_release BIND Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Simon Glass <sjg@chromium.org>
| * devres: make Devres optional with CONFIG_DEVRESMasahiro Yamada2015-08-06-2/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, Devres requires additional 16 byte for each allocation, which is not so insignificant in some cases. Add CONFIG_DEVRES to make this framework optional. If the option is disabled, devres functions fall back to non-managed variants. For example, devres_alloc() to kzalloc(), devm_kmalloc() to kmalloc(), etc. Because devres_head is also surrounded by an ifdef conditional, there is no memory overhead when CONFIG_DEVRES is disabled.

| * devres: introduce Devres (Managed Device Resource) frameworkMasahiro Yamada2015-08-06-1/+374
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In U-Boot's driver model, memory is basically allocated and freed in the core framework. So, low level drivers generally only have to specify the size of needed memory with .priv_auto_alloc_size, .platdata_auto_alloc_size, etc. Nevertheless, some drivers still need to allocate/free memory on their own in case they cannot statically know the necessary memory size. So, I believe it is reasonable enough to port Devres into U-boot. Devres, which originates in Linux, manages device resources for each device and automatically releases them on driver detach. With devres, device resources are guaranteed to be freed whether initialization fails half-way or the device gets detached. The basic idea is totally the same to that of Linux, but I tweaked it a bit so that it fits in U-Boot's driver model. In U-Boot, drivers are activated in two steps: binding and probing. Binding puts a driver and a device together. It is just data manipulation on the system memory, so nothing has happened on the hardware device at this moment. When the device is really used, it is probed. Probing initializes the real hardware device to make it really ready for use. So, the resources acquired during the probing process must be freed when the device is removed. Likewise, what has been allocated in binding should be released when the device is unbound. The struct devres has a member "probe" to remember when the resource was allocated. CONFIG_DEBUG_DEVRES is also supported for easier debugging. If enabled, debug messages are printed each time a resource is allocated/freed. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Simon Glass <sjg@chromium.org>
| * dm: add DM_FLAG_BOUND flagMasahiro Yamada2015-08-06-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Currently, we only have DM_FLAG_ACTIVATED to indicate the device status, but we still cannot know in which stage is in progress, binding or probing. This commit introduces a new flag, DM_FLAG_BOUND, which is set when the device is really bound, and cleared when it is unbound.
