problem：
How to add your own infrared user code to the power. c file code in the BL30 project?

My remote control’s user code is 04cb;

In the following array list, the last four digits represent the user code, so how are the preceding numbers calculated?

Please let me know, thank you！

static IRPowerKey_t prvPowerKeyList[] = {
	{ 0xef10fe01, IR_NORMAL}, /* ref tv pwr */
	{ 0xba45bd02, IR_NORMAL}, /* small ir pwr */
	{ 0xef10fb04, IR_NORMAL}, /* old ref tv pwr */
	{ 0xf20dfe01, IR_NORMAL},
	{ 0xe51afb04, IR_NORMAL},
	{ 0x3ac5bd02, IR_CUSTOM},

@Lexus 2 digit key value inverse code+2 digit key value code+4 digit user code. For example, the khadas ir remote control sets the power key to wake up.

2 digit key value inverse code+2 digit key value code+4 digit user code:
key^(0xeb) + key(0x14) + customcode（0xff00） = 0xeb14ff00
