firmware-utils: tplink-safeloader: refactor meta-partition padding
Because some padding values in the TP-Link safeloader image generation were hardcoded, different values were sometimes used throughout a factory image. TP-Link's upgrade images use the same value everywhere, so let's do the same here. Although a lot of TP-Link's safeloader images have padded partition payloads, images for the EAP-series of AC devices don't. This padding is therefore also made optional. By replacing the type of the padding value byte with a wider datatype, new values outside of the previously valid range become available. Use these new values to denote that padding should not be performed. Because char might be signed, also replace the char literals by a numeric literal. Otherwise '\xff' might be sign extended to 0xffff. This results in factory images differing by 1 byte for: * C2600 * ARCHER-C5-V2 * ARCHERC9 * TLWA850REV2 * TLWA855REV1 * TL-WPA8630P-V2-EU * TL-WPA8630P-V2-INT * TL-WPA8630P-V2.1-EU * TLWR1043NDV4 * TL-WR902AC-V1 * TLWR942NV1 * RE200-V2 * RE200-V3 * RE220-V2 * RE305-V1 * RE350-V1 * RE350K-V1 * RE355 * RE450 * RE450-V2 * RE450-V3 * RE500-V1 * RE650-V1 The following factory images no longer have padding, shrinking the factory images by a few bytes for: * EAP225-OUTDOOR-V1 * EAP225-V3 * EAP225-WALL-V2 * EAP245-V1 * EAP245-V3 Signed-off-by: Sander Vanheule <sander@svanheule.net>
