2017-07-19efi_loader: correctly implement 100ns conversionxypron.glpk@gmx.de
In efi_set_timer we receive the trigger time in intervals of 100 ns. We should convert it to intervals of 1000 ns by 64bit division. The patch supplies function efi_div10 that uses multiplication to implement the missing 64 bit division.

2017-07-19efi_loader: correct size for tpl levelxypron.glpk@gmx.de
The UEFI standard defines the type for the tpl level as EFI_TPL alias UINTN. UINTN is an integer is defined as an unsigned integer of native width. So we can use size_t for the definition. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

2017-07-19efi_loader: disk: iterate only over valid block devicesxypron.glpk@gmx.de
The efi_loader currently stops iterating over the available block devices stopping at the first device that fails. This may imply that no block device is found. With the patch efi_loader only iterates over valid devices. It is based on patch 06d592bf52f6 (dm: core: Add uclass_first/next_device_check()) which is currently in u-boot-dm.git. For testing I used an odroid-c2 with a dts including &sd_emmc_a { status = "okay"; }; This device does not exist on the board and cannot be initialized. Without the patch: => bootefi hello ## Starting EFI application at 01000000 ...

2017-07-19bootefi: allow return without EFI_BOOT_SERVICES.Exitxypron.glpk@gmx.de
The Unified Extensible Firmware Interface Specification, version 2.7, defines in chapter 2.1.2 - UEFI Application that an EFI application may either directly return or call EFI_BOOT_SERVICES.Exit(). Unfortunately U-Boot makes the incorrect assumption that EFI_BOOT_SERVICES.Exit() is always called. So the following application leads to a memory exception on the aarch64 architecture when returning: EFI_STATUS efi_main( EFI_HANDLE handle, EFI_SYSTEM_TABlE systable) { return EFI_SUCCESS; } With this patch the entry point is stored in the image handle. The new wrapper function do_enter is used to call the EFI entry point. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

2017-07-19efi_loader: reimplement efi_locate_protocolxypron.glpk@gmx.de
The UEFI specification requires that LocateProtol finds the first handle supporting the protocol and to return a pointer to its interface. So we have to assign the protocols to an efi_object and not use any separate storage. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

2017-07-19efi_loader: implement LocateHandleBufferxypron.glpk@gmx.de
UEFI boot service LocateHandleBuffer is implemented by calling efi_allocate_handle and efi_locate_handle. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2017-07-19efi_loader: refactor efi_locate_handlexypron.glpk@gmx.de
To implement LocateHandleBuffer we need to call efi_locate_handle internally without running through EFI_EXIT. So put EFI_ENTRY and EFI_EXIT into a new wrapper function efi_locate_handle_ext. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

2017-07-19efi_loader: refactor efi_open_protocolxypron.glpk@gmx.de
efi_open_protocol was implemented to call a protocol specific open function to retrieve the protocol interface. The UEFI specification does not know of such a function. It is not possible to implement InstallProtocolInterface with the current design. With the patch the protocol interface itself is stored in the list of installed protocols of an efi_object instead of an open function.

2017-07-11dm: ofnode: use fdt32_t for DT property value to fix sparse warningMasahiro Yamada
DTB is encoded in big endian. When we retrieve property values, we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion. This is a bit error-prone, but sparse is useful to detect endian mismatch. We need to use (fdt32_t *) instead of (u32 *) for a pointer of a property value. Otherwise sparse warns "cast to restricted __be32". Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2017-07-11dm: ofnode: rename ofnode_read_prop() to ofnode_get_property()Masahiro Yamada
This function returns the pointer to the value of a node property. The current name ofnode_read_prop() is confusing. Follow the naming of_get_property() from Linux. The return type (const u32 *) is wrong. DT property values can be strings as well as integers. This is why of_get_property/fdt_getprop returns an opaque pointer.
