To: u-boot
Restructure clock manager driver in the preparation to support A10.
Move the Gen5 specific code to _gen5 files.
- Change all uint32_t to u32 and change to use macro BIT(n) for bit shift.
- Check return value from wait_for_bit(). So change return type to int for
cm_write_with_phase() and cm_basic_init().

From: Ley Foon Tan @ 2017-04-19 9:29 UTC (permalink / raw)
To: u-boot
Restructure reset manager driver in the preparation to support A10.
Move the Gen5 specific code to gen5 files. Change socfpga_per_reset() return type to int.

16 siblings, 0 replies; 34+ messages in thread
From: Ley Foon Tan @ 2017-04-19 9:29 UTC (permalink / raw)
To: u-boot
Restructure misc driver in the preparation to support A10.
Move the Gen5 specific code to gen5 file.
Change all uint32_t_to u32 and check return value from
socfpga_bridges_reset.

If you keep this patch the way it is, this will cause the Atlas board to
hang here.

Hi Dalon,
Can you check this patch? On the Atlas board, I'm seeing the call to
socfpga_bridges_reset(0) fail because fpgamgr_test_fpga_ready() is
failing, because is_fpgamgr_initdone_high() is returning 0.

I ran this on the c5 socdk and noticed the same behavior as Dinh, then realized
the board was setup to configure the fpga independently of the processor. When
i change the MSELs on the board to ensure the FPGA is unconfigured the code
fails in the same location where init done is not high. It is definitely an
expected use case in c5/a5 that uboot can run without the fpga configured at
all.

My proposal is revert back to its original code, revert
socfpga_bridges_reset() return type to void and don't check error from
fpgamgr_test_fpga_ready(). So, we can support Gen5 boot without
program FPGA.
Thanks.

Isn't the difference between CV/AV and A10 such that the former can boot
without programmed FPGA while the later can NOT boot without programmed
FPGA ? So this code is A10 specific ?

Yes, at a minimum in A10 the IO ring needs to be configured prior to boot.
Since these functions (socfpga_bridges_reset) are different for c5/a5 and a10,
i would suggest changing the code to enable the bridges IF the fpga is
configured. perhaps just:
...
} else {
writel(0, &sysmgr_regs->iswgrp_handoff[0]);
writel(l3mask, &sysmgr_regs->iswgrp_handoff[1]);
/* Check signal from FPGA. */
if (!fpgamgr_test_fpga_ready()) {
/* brdmodrst */
writel(0, &reset_manager_base->brg_mod_reset);
}
...
I think this actually mirrors the behavior of the 2013.01.01 fork where if the
fpga is configured, spl enables the bridges.

We do the IOCSR configuration on C5/A5 too, so what's the difference ?

in c5/a5 the iocsr config is done directly, the iocsr data is compiled into spl,

So that's why the FPGA must always be programmed with something to get
the A10 working ? I see ... thanks for clarifying.

Code above will reset bridge if FPGA configuration is failed. So, it
should be something like this (original code):
...
} else {
writel(0, &sysmgr_regs->iswgrp_handoff[0]);
writel(l3mask, &sysmgr_regs->iswgrp_handoff[1]);
/* Check signal from FPGA. */
if (!fpgamgr_test_fpga_ready()) {
/* FPGA not ready, do nothing. */
printf("%s: FPGA not ready, aborting.\n", __func__);
return;
}
/* brdmodrst */
writel(0, &reset_manager_base->brg_mod_reset);
/* Remap the bridges into memory map */
writel(l3mask, SOCFPGA_L3REGS_ADDRESS);
}
