54  * efi_to_native() - convert the UEFI variable name and vendor GUID to U-Boot
55  *		     variable name
57  * The U-Boot variable name is a concatenation of prefix 'efi', the hexstring
58  * encoded vendor GUID, and the UTF-8 encoded UEFI variable name separated by
61  * @native:		pointer to pointer to U-Boot variable name
62  * @variable_name:	UEFI variable name
102  * parse_attr() - decode attributes part of variable value
104  * Convert the string encoded attributes of a UEFI variable to a bit mask.
107  * @str:	value of U-Boot variable
109  * Return:	pointer to remainder of U-Boot variable value
149  * efi_efi_get_variable() - retrieve value of a UEFI variable
156  * @variable_name:	name of the variable
158  * @attributes:		attributes of the variable
159  * @data_size:		size of the buffer to which the variable value is copied
160  * @data:		buffer to which the variable value is copied
245  * parse_uboot_variable() - parse a u-boot variable and get uefi-related
247  * @variable:		whole data of u-boot variable (ie. name=value)
249  * @variable_name:	name of uefi variable in u16, null-terminated
253  * A uefi variable is encoded into a u-boot variable as described above.
254  * This function parses such a u-boot variable and retrieve uefi-related
256  * is the size of variable name including NULL.
