LS2160AQDS supports 3 serdes, devided into 6 slots.

The RCW directories names for the LS2160AQDS boards conform to the following
naming convention:

abcd_efgh_ijkl_mnop_qrst_uvwx_RR_A_B_C:

For Serdes1:

c = What is available on serdes 1 slot 1, LANE 2
d = What is available on serdes 1 slot 1, LANE 3
e = What is available on serdes 1 slot 2, LANE 4
f = What is available on serdes 1 slot 2, LANE 5
g = What is available on serdes 1 slot 2, LANE 6
h = What is available on serdes 1 slot 2, LANE 7

For Serdes2:
i = What is available on serdes 2 slot 3, LANE 0
j = What is available on serdes 2 slot 3, LANE 1
k = What is available on serdes 2 slot 3, LANE 2
l = What is available on serdes 2 slot 3, LANE 3
m = What is available on serdes 2 slot 4, LANE 4

For the Serdes(6 Slots) Lanes (a..x):
 'N' is NULL, not available/not used
 'H' is SATA
 'S' is SGMII
 'P' is PCIe
 'F' is XFI/USXGMII
 'G' is 25G
 'L' is 50G
 'X' is 40G
 'C' is 100G

RGMII Interface (R):
  'R' is RGMII Interface 1G

Serdes1 protocol (A):
A = 'serdes1 protocol value (decimal)'

Serdes2 protocol (B):
B = 'serdes2 protocol value (decimal)'

Serdes3 protocol (C):

Ref clock setting on board
==========================
DDR Ref clock: 100 MHz
Sys PLL Ref clock: 100MHz

Files naming convention
=============================
rcw_x_l_m_n.rcw
rcw_x_l_m_n_bootmode.rcw
rcw_x_y_l_m_n.rcw
rcw_x_y_z_l_m_n.rcw

x = Core frequency
y = Platform frequency
z = DDR frequency
bootmode = nor(default)/sd
l = 'serdes1 protocol value'
m = 'serdes2 protocol value'
n = 'serdes3 protocol value'

For example,
  rcw_2000_19_5_2.rcw means rcw for core frequency of 2000MHz, with serdes1=19 serdes2=5 serdes3=2.
  rcw_2000_700_19_5_2.rcw means rcw for core frequency 2000MHz and Platform frequecny 700MHz, with serdes1=19 serdes2=5 serdes3=2.
  rcw_2000_700_2400_19_5_2.rcw means rcw for core frequency 2000MHz, Platform frequecny 700MHz and DDR Memory Data Rate as 2400 MT/s, with serdes1=19 serdes2=5 serdes3=2.
  rcw_2000_19_5_2_sd.rcw means rcw for core frequency of 2000MHz with SD boot, with serdes1=19 serdes2=5 serdes3=2.

DSPI Enablement
===============
SDHC & SPI lanes are muxed.
Below RCW Fields should be modified in order to access DSPI flashes.

1) For DSPI1:- Set RCW field 'SDHC1_BASE_PMUX' to 2.
2) For DSPI2:- Set RCW field 'SDHC2_BASE_PMUX' to 2.
3) For DSPI3:- Set RCW field 'IIC5_PMUX' to 3.
             - Set RCW field 'SDHC1_BASE_PMUX' to 3.
             - Set RCW field 'SDHC1_DS_PMUX' to 2.
             - Set RCW field 'SDHC1_DIR_PMUX' to 3 (FOR PCS1,PCS2 & PCS3)
