2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-01core: ofnode: Fix translation for #size-cells == 0Mario Six
Commit 286ede6 ("drivers: core: Add translation in live tree case") made dev_get_addr always use proper bus translations for addresses read from the device tree. But this leads to problems with certain busses, e.g. I2C busses, which run into an error during translation, and hence stop working. It turns out that of_translate_address() and fdt_translate_address() stop the address translation with an error when they're asked to translate addresses for busses where #size-cells == 0 (comment from drivers/core/of_addr.c): * Note: We consider that crossing any level with #size-cells == 0 to mean * that translation is impossible (that is we are not dealing with a value * that can be mapped to a cpu physical address). This is not really specified * that way, but this is traditionally the way IBM at least do things To fix this case, we check in both the live-tree and non-live tree-case, whether the bus of the device whose address is about to be translated has size-cell size zero. If this is the case, we just read the address as a plain integer and return it, and only apply bus translations if the size-cell size if greater than zero.

2018-01-22efi_driver: EFI block driverHeinrich Schuchardt
This patch provides * a uclass for EFI drivers * a EFI driver for block devices For each EFI driver the uclass * creates a handle * adds the driver binding protocol The uclass provides the bind, start, and stop entry points for the driver binding protocol. In bind() and stop() it checks if the controller implements the protocol supported by the EFI driver. In the start() function it calls the bind() function of the EFI driver. In the stop() function it destroys the child controllers. The EFI block driver binds to controllers implementing the block io protocol. When the bind function of the EFI block driver is called it creates a new U-Boot block device. It installs child handles for all partitions and installs the simple file protocol on these. The read and write functions of the EFI block driver delegate calls to the controller that it is bound to. A usage example is as following: U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and exposes a handle with the block IO protocol. It calls ConnectController. Now the EFI block driver installs the partitions with the simple file protocol. iPXE uses the simple file protocol to load Grub or the Linux Kernel.

2018-01-22dm: add dev_read_u32()Masahiro Yamada
dev_read_u32_default() always returns something even when the property is missing. So, it is impossible to do nothing in the case. One solution is to use ofnode_read_u32() instead, but adding dev_read_u32() will be helpful. BTW, Linux has an equvalent function, device_property_read_u32(); it is clearer that it reads a property. I cannot understand the behavior of dev_read_u32() from its name. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2017-10-04dm: define dev_*() log functions in DM headerMasahiro Yamada
Many drivers had started to use dev_err, dev_info, etc. for log functions. Currently, we are relying on <linux/compat.h>, but I guess the best home is <dm/device.h>, taking into account that Linux defines them in <linux/device.h>. For now, I am leaving the ones in <linux/compat.h> because lots of Linux-originated code uses dev_*(), but the first argument is not struct udevice, so we need to ignore the bogus argument.

This function is usefull to get phandle number contained in a property list.

To implement it, either of_count_phandle_with_args() or fdtdec_parse_phandle_with_args() are used respectively for live tree and flat tree. By passing index = -1, these 2 functions returns the number of phandle contained into the property list.
