Subject: [PATCH v2 08/10] microblaze: add Kconfig symbol for the vector base address
Date: Tue, 30 Nov 2021 18:33:55 +0200	[thread overview]
Message-ID: <20211130163358.2531677-8-ovidiu.panait@windriver.com> (raw)
In-Reply-To: <20211130163358.2531677-1-ovidiu.panait@windriver.com>

MicroBlaze vector base address is configurable (hdl C_BASE_VECTORS
configuration parameter). Current code assumes that the reset vector
location is always 0x0.

Add the XILINX_MICROBLAZE0_VECTOR_BASE_ADDR Kconfig option so the user
can adjust the reset vector address.

Signed-off-by: Ovidiu Panait <ovidiu.panait@windriver.com>

Changes in v2:
Added Kconfig option description.
