2017-07-19efi_loader: implement EFI_DEVICE_PATH_TO_TEXT_PROTOCOLxypron.glpk@gmx.de
ConvertPathToText is implemented for * type 4 - media device path * subtype 4 - file path This is the kind of device path we hand out for block devices. All other cases may be implemented later.

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: provide a sufficient number of protocolsxypron.glpk@gmx.de
Four protocols per object is too few to run iPXE. Let's raise the number of protocols per object to eight. 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: implement InstallMultipleProtocolInterfacesxypron.glpk@gmx.de

2017-07-19efi_loader: refactor efi_uninstall_protocol_interfacexypron.glpk@gmx.de
For the implementation of UninstallMultipleProtocolInterfaces we need to call efi_uninstall_protocol_interface. In internal calls we should not pass through EFI_EXIT. The patch introduces a wrapper function efi_uninstall_protocol_interface_ext. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

2017-07-19efi_loader: implement InstallProtocolInterfacexypron.glpk@gmx.de
efi_install_protocol_interface up to now only returned an error code. The patch implements the UEFI specification for InstallProtocolInterface with the exception that it will not create new handles.

2017-07-19efi_loader: efi_open_protocol: parameter checksxypron.glpk@gmx.de
Add all parameter checks for function efi_open_protocol that do not depend on a locking table. 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.
