[U-Boot] [PATCH 1/3] fsl_sec: fix register layout on Layerscape architectures

[U-Boot] [PATCH 1/3] fsl_sec: fix register layout on Layerscape architectures

[laurentiu.tudor at nxp.com]

From: Laurentiu Tudor <laurentiu.tudor@nxp.com>

On Layerscape architectures the SEC memory map is 1MB and the
register blocks contained in it are 64KB aligned, not 4KB as
the ccsr_sec structure currently assumes. Fix the layout of
the structure for these architectures.

[U-Boot] [PATCH] pci: layerscape: add option to statically allocate PCI StreamIDs

[laurentiu.tudor at nxp.com]

From: Laurentiu Tudor <laurentiu.tudor@nxp.com>

Certain PCI scenarios have more dynamic requirements, e.g. endpoints
are "hot-plugged" later in the system lifetime. Add a Kconfig option
that allows specifying a maximum number of end-points, per PCI controller
and allocate a StreamID for each one.

Why to continue if we are out of stream-ids?

We can error out when out of LUT entry

[U-Boot] [upstream-release] [PATCH] pci: layerscape: add option to statically allocate PCI StreamIDs

[Laurentiu Tudor]

Hi Bharat,

Actually I've sent this patch by mistake, sorry for that.
I'll drop it and resend the patch series.

As per my understanding, the BUS number in our SOCs would always be 0 for each PCIE controller.
Only the device number and function number would change depending on the device(s) attached to PCIE controller.

Wouldn't the better alternative is to fix some stream IDs against BDF in device tree itself for all the PCIE devices that we know for sure would be attached to board.
And limit the available streamIDs to be used by bootloader for dynamically discovered PCIE devices.

[U-Boot] [PATCH 2/3] armv8: fsl-layerscape: fix SEC QI ICID setup

[laurentiu.tudor at nxp.com]

From: Laurentiu Tudor <laurentiu.tudor@nxp.com>

The SEC QI ICID setup in the QIIC_LS register is actually an offset
that is being added to the ICID coming from the qman portal. Setting
it with a non-zero value breaks SMMU setup as the resulting ICID is
not known. On top of that, the SEC QI ICID must match the qman portal
ICIDs in order to share the isolation context.

[U-Boot] [PATCH 3/3] armv8: fsl-layerscape: avoid DT fixup warning

[laurentiu.tudor at nxp.com]

From: Laurentiu Tudor <laurentiu.tudor@nxp.com>

sec_firmware reserves JR3 for it's own usage and deletes the JR3 node
from the device tree. This causes this warning to be issued when doing
the device tree fixup:

WARNING could not find node fsl,sec-v4.0-job-ring: FDT_ERR_NOTFOUND.

Fix it by excluding the device tree fixup for the JR reserved by
sec_firmware.

Do you think it is fair to assume that firmware will always reserve JR3? 

Thanks
