Hi Alamy,

Could you help to verify if this patch works well on Cypress platform? I verified some of the single CPU platforms so I believe it should be fine for all the other single CPU platforms.

Thanks.

Hi,

The existing section 'TFM_UNPRIV_DATA' now holds nothing - it was designed for holding some data belong to the unprivileged code block, while now the unprivileged code is required as read-only and no place for its read-write data.

Remove this section as it is unused; also remove those code objects exists in the unprivileged code section but has read-write data: 'platform_retarget_dev.o' and 'device_definition.o'.

This patch changes some sources inside the platforms, so the platform owner please help to check if that matters:

Thanks.
