Hi guys,
Your help is much appreciated.
Please see below the code piece enabling the CPU1:
...
if (cpu_is_imx7d()) {
/* enable core */
if (enable)
imx_gpcv2_set_core1_pdn_pup_by_software(false);
mask = 1 << (BP_SRC_A7RCR1_A7_CORE1_ENABLE + cpu - 1);
val = readl_relaxed(src_base + SRC_A7RCR1);
val = enable ? val | mask : val & ~mask;
writel_relaxed(val, src_base + SRC_A7RCR1);
}
...
Kind rgeards,
Ilya.
