LS2088 TFA: ATF with static ddr init for 2 controllers

Rohanraj — Thu, 12 Aug 2021 04:06:04 GMT

We have custom designed board based on Ls2088ardb. We currently have PPA++uboot working but trying to convert it to TFA boot.

As per user Gide I have created _ddr_init() and board_static_ddr() function as below.

```

long long board_static_ddr(struct ddr_info *priv)
{
if(priv->ddr[0] == (void *)NXP_DDR_ADDR)
{
memcpy(&priv->ddr_reg, &static_2132, sizeof(static_2132));
}
else
{
memcpy(&priv->ddr_reg, &static_2132_2, sizeof(static_2132_2));
}

return ULL(0x200000000);
}

long long _init_ddr(void)
{
Int spd_addr[] = { 0x51, 0x52, 0x53, 0x54 };
struct ddr_info info;
struct sysinfo sys;
long long dram_size;

zeromem(&sys, sizeof(sys));
get_clocks(&sys);
debug("platform clock %lu\n", sys.freq_platform);
debug("DDR PLL1 %lu\n", sys.freq_ddr_pll0);
debug("DDR PLL2 %lu\n", sys.freq_ddr_pll1);

zeromem(&info, sizeof(info));

/* Set two DDRC. Unused DDRC will be removed automatically. */
info.num_ctlrs = 1;
info.spd_addr = spd_addr;
Info.ddr[0] = (void *)NXP_DDR_ADDR;
//info.ddr[1] = (void *)NXP_DDR2_ADDR;
info.clk = get_ddr_freq(&sys, 0);
If (!info.clk)
info.clk = get_ddr_freq(&sys, 1);
info.dimm_on_ctlr = 1;

dram_size = dram_init(&info);

info.ddr[0] = (void *)NXP_DDR2_ADDR;
dram_size = dram_init(&info);

if (dram_size < 0)
ERROR("DDR init failed.\n");

return dram_size;
}

```

After compiling PBL for QSPI and BL33 fip binary when I fash it, I do not see any data on UART after the controller reset.

Is there anything I am missing?

Please refer to flexbuild_lsdk2012/packages/firmware/atf/plat/nxp/soc-ls1046/ls1046ardb/ddr_init.c for functions board_static_ddr and _init_ddr definition. Please Define macro “CONFIG_STATIC_DDR” in plat/nxp/<SOC>/<BOARD>/plafform_def.h.

In addition, please customize RCW file in packages/firmware/rcw/ls2088ardb/FFFFFFFF_PP_HH_0x2a_0x41/rcw_2000_qspi.rcw according to your custom board.

Please program pbl image at 0x0, program fip.bin at 0x100000.
