The script based firmware loader does not use anything from the fs_loader implementation. Separate it into its own library source file and convert the mediatek PHY to use this separate code. This should reduce the amount of code that is pulled in alongside the firmware loader, as the FS loader is no longer included. Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org>

/**
|
|
* request_firmware_into_buf_via_script() -
|
|
* Load firmware using a U-Boot script and copy to buffer
|
|
* @buf: Pointer to a pointer where the firmware buffer will be stored.
|
|
* @max_size: Maximum allowed size for the firmware to be loaded.
|
|
* @script_name: Name of the U-Boot script to execute for firmware loading.
|
|
* @retsize: Return the actual firmware data size (optional).
|
|
*
|
|
* Executes a U-Boot script (@script_name) that loads firmware into
|
|
* memory and sets the environment variables 'fw_addr' (address) and
|
|
* 'fw_size' (size in bytes). On success, copies the firmware
|
|
* from the given address to user buffer @buf.
|
|
*
|
|
* The script must set these environment variables:
|
|
* fw_addr - Address where firmware is loaded in memory
|
|
* fw_size - Size of the firmware in bytes
|
|
*
|
|
* The script should be defined in the U-Boot environment, for example:
|
|
* env set script_name 'load mmc 0:1 ${loadaddr} firmware.bin &&
|
|
* env set fw_addr ${loadaddr} && env set fw_size ${filesize}
|
|
* Return: 0 on success, negative value on error.
