function 1: modify ddr.bin file from ddrbin_param.txt.
	1) modify 'ddrbin_param.txt', set ddr frequency, uart info etc what you want.
	   If want to keep items default, please keep these items blank.
	2) run 'ddrbin_tool' with argument 1: ddrbin_param.txt, argument 2: ddr bin file.
	   like: ./ddrbin_tool ddrbin_param.txt px30_ddr_333MHz_v1.13.bin

function 2: get ddr.bin file config to gen_param.txt file
	If want to get ddrbin file config, please run like that:
	./ddrbin_tool -g gen_param.txt px30_ddr_333MHz_v1.15.bin
	The config will show in gen_param.txt.

* DDR frequencies(add more)

ddr2_f1_freq_mhz: ddr2 frequency fsp 1,  unit:MHz.
ddr2_f2_freq_mhz: ddr2 frequency fsp 2,  unit:MHz.
ddr2_f3_freq_mhz: ddr2 frequency fsp 3,  unit:MHz.
ddr2_f4_freq_mhz: ddr2 frequency fsp 4,  unit:MHz.
ddr2_f5_freq_mhz: ddr2 frequency fsp 5,  unit:MHz.
...
The ddrx_f0_freq_mhz(the fsp0 frequency) is named ddrx_freq.

ddr*_f*_freq_mhz/lp*_f*_freq_mhz: Only RV1126/RV1109, RK3566/RK3568, RK3588 used.
The program will initialize dram by following order.
for example: ddr4_f1_freq_mhz --> ddr4_f2_freq_mhz --> ddr4_f3_freq_mhz --> ddr4_freq.
And the final frequency is ddr4_freq to boot system.
The ddr frequency table in kernel dts/dtsi file need correspond to these frequencies.
So it is better to arrange the frequency values in order as above. That means the max freq is in final freq(lp*/ddr*_freq) and the min freq is in 'ddr*/lp*_f1_freq_mhz'.
Such as:	ddr*/lp*_f1_freq_mhz < ddr*/lp*_f2_freq_mhz < ddr*/lp*_f3_freq_mhz < lp*/ddr*_freq(the final freq)
For example:
	...
	ddr4_freq=1560
	...
	ddr4_f1_freq_mhz=324
	ddr4_f2_freq_mhz=528
	ddr4_f3_freq_mhz=780
	...

Note: The ddr frequency table in kernel dts/dtsi file need correspond to these frequencies.

* SR PD idle

sr_idle: auto self-refresh mode delay time.
pd_idle: auto power-down mode delay time.

* DDR 2T

These parameters are about Spread Spectrum Modulator(ssmod) for PLL.
ssmod_downspread: ssmod work mode. 1: down spread, 0: center spread.
ssmod_div: Divider required to set the modulation frequency. RK3308 suggests to ssmod_div=2, others platforms suggest to ssmod_div=5.
ssmod_spread: spread amplitude % = 0.1 * ssmod_spread; 0: disable ssmod, others will enable ssmod, max to 0x1f.
